Neurons are fundamental units of the nervous system, playing a critical
role in transmitting information throughout the body. Here are the key
facts known about neurons:
Structure: Neurons consist of three main parts:
Cell Body (Soma): Contains the nucleus and other organelles, responsible
for metabolic activities.
Dendrites: Branch-like extensions that receive signals from other neurons
or sensory receptors.
Axon: Long fibre that transmits signals away from the cell body to
other neurons,
muscles, or glands.
Function: Neurons transmit electrochemical signals. The signal typically
travels from dendrites, through the cell body, down the axon, and to the
axon terminals, where it stimulates the release of neurotransmitters.
Types: Neurons can be classified based on their function and structure:
Sensory Neurons: Transmit sensory information from sensory organs to the
central nervous system.
Motor Neurons: Carry signals from the central nervous system to muscles and
glands.
Interneurons: Found exclusively in the central nervous system, they connect
sensory and motor neurons and process information.
Neurotransmission: The process by which neurons communicate:
Action Potential: An electrical signal that travels down the axon when a
neuron is stimulated.
Synapse: Junction between neurons where neurotransmitters are released from
the axon terminal of one neuron and received by receptors on the dendrites
of another neuron.
Plasticity: Neurons exhibit plasticity, meaning they can change their
structure and function in response to experience, learning, and injury.
Supporting Cells: Neurons are supported and protected by other types of
cells in the nervous system, including:
Glial Cells: Provide structural support, insulation (myelin sheath), and
nutrients to neurons. Types include oligodendrocytes (CNS) and Schwann
cells (PNS).
Neurological Disorders: Dysfunction or damage to neurons can lead to
various neurological disorders, such as Alzheimer's disease, Parkinson's
disease, multiple sclerosis, and others.
Development: Neurons develop from neural stem cells during embryonic
development, with intricate processes guiding their migration,
differentiation, and formation of connections.
Quantitative Aspects: The human brain contains about 86 billion neurons on
average, but this number can vary significantly among individuals.
Research and Technology: Advances in neuroscience, including imaging
techniques like fMRI and EEG, have enabled researchers to study neuron
activity and connectivity in greater detail. San Diego center where our Indian
American brilliant combining our literature described the vast orientations
of the brain where that standard itself is stated to be tip of the ice-berg.
II The word ‘mind’ literally means ‘measuring’; and it has been
used in this sense in the Vedas and the Brāhmaṇas from early times. It is a
subtle matter in all philosophy. It has been considered to be the part of
that which was designated by its name manas. It is an activity in the life
of man and it measures his wisdom, pleasures, pain, feelings etc. It seems
that the problem of the nature of mind and its relation to matter may be
satisfactorily solved only if we think of mind as a higher form of matter
capable of reflecting the nature of self which is consciousness. This mind
or manas has no concrete place. It is the name given to a series of
conscious activities such as desire, aversion, pleasure, pain,
intelligence, thought etc, and this mind is capable of referring to the
past, present and future.
Apart from the qualities of the mind it is very difficult to know the pure
self at the empirical level.
“The mind is the material part of the external world. It belongs to us but
it does not explain who we really are, just as our house belongs to us but
is not us. This may be a shocking matter to consider, but it is really
something intuitively known to us. When we speak of ‘my mind’, we are
defining the mind as an object which belongs to us and not as ourselves”
The mind has a material structure; and it works as an instrument or
tool. The sense organs themselves are instruments. The eye is an instrument
of seeing; the ear is an instrument of hearing and so on. Similarly, the
mind that works to process sensory information is itself an instrument. The
mind is the main instrument we use to function in life. It is organically
related to our physical body. So, the mind is also a kind of body organ.
The physical body is primarily an organ of perception and expression. It is
structured mainly by our sense the motor organs like the sound and hands
through which we express ourselves. The mind can function apart from body
consciousness as in sleep, trance and after death states.
The reference to mind can be found in the Vedas from the beginning.
The first germ of mind can be radical in the lust or wish. It is desire for
individual pleasure. In the Rigvedic hymns it is said:
Kāmas tada gresama varttatādhi manasu retaḥ prathamaṃ yadāsīt || [2]
>From these days the philosophers were interested in understanding and
controlling the mental processes. Mind originates from the root ‘man’ ‘to
think’ and the word ‘citta’ is used at some places almost synonymous to
mind and it has been used in this sense in the early Vedas, Brāhmaṇas and
Upanisads. It is the recording faculty and it receives impressions gathered
by the sense organs from the outside world. It seems to be regarded to
attend to all the cognitive, affective and conative processes
It is that the gods know the mind of man who proposes and passes on through
the breath to be the wind and tells the gods what the mind of man is.
>From the beginning such a concept of mind can be found in the Vedas
themselves.
The famous Gāyatri mantra in the Ṛgveda and in the Yajurveda reveals the
way in which the consciousness pervades the Vedic prayers:
oṃ bhurbhuvasvaḥ tat saviturvareṇyam bhargodevasya dhīmahī dhiyo yona
pracodayāt ||
This mantra was revealed by sage Viśamitra. It is named after its metre
Gāyatri which means ‘the saviour of the singer’. It is looked upon as the
essence of the Vedas. The essence of the prayer is ‘stimulation of one’s
intellect; and enlightening of one’s mind’.
Another great Vedic hymn desires that man’s resolutions should be
auspicious verses: -
suṣā rathiraś vani vayen manuṣyān nenīyathe' śubhir vājinaiva hṛd
pratiṣṭhayaṃ yadaciraṃ javiṣṭam manme manaḥ śiva saṅkalpamastu |[5]
It is the fantastic verses about mind. It says that mind is considered as
the swiftest, and it is seated in the heart and also unmortified. It is the
controller of the sense organs. These verses also indicate the necessity of
controlling the mind. In the Vedic texts, there are numerous references to
mind as being located in the heart. The Yajurveda declares that the mind is
the means of knowledge. The mind is considered as manana śīlaṃ jñānasā
dhanam. Mind is sarva karma sādhanam. In the Ṛgveda the mind occupies a
major part of logical thinking and discussions. Mind can be truthful,
unruffled, mature, firm and sharp. The mind has been considered as a lord
of the body, showing the significance of mind over the body. The
description of mind in the Ṛgveda comes in the context of alcoholic
intoxication. Alternatively indicates that soma-rasa (THOUGHT-PROCESS)
envelopes the mind and it produces a marked effect on the sense organs. The
‘Nāsadīyasūkta’ of the Ṛgveda indicates the important role of mind in human
life. The word ‘citta’ is used at some places almost synonymous to mind.
The Ṛgveda states that intellect is the swiftest of birds. It is:
mano javiṣṭaṃ patayatsu antaḥ || [13]
The Ṛgvedic hymns proclaim the unity among the people and maintain the
unity for mankind.
The mind can play the main role of universal unity. It preaches that:-
saṃgacchadhvaṃ saṃvadadhvaṃ saṃ vo manāṃsijānatāṃ devā bhāgaṃ yathā pūrve
saṃjānānā upāsate | samāno mantraḥ samitiḥ samānī samānaṃ manaḥ saha cittaṃ
eṣāṃ samānaṃ mantraṃ abhimantraye vaḥ samānena vo haviṣā juhomi || samānī
va akūtiḥ samānā hṛdayāni vaḥ samānaṃ astu vo mano yathā vaḥ sa sahāsati ||
[14]
Mind in the Saṃhitas and the Brāhmaṇas is the pure sensory organ or it is
possible intellect. It is identified with the Being. The Carakasaṃhita
states that knowledge is the character of mind and that mind and knowledge
are interrelated. In the absence of mind, knowledge gets vanished.
So knowledge is the attribute of mind. It says:
lakṣaṇaṃ manasu jñāna syābhāvo bhāva eva ca || [15]
The Yogavāsiṣṭa discusses the mind of which the characters are declared as
abstractive forms. It states: -
saṅkalpanaṃ mano viddhi saṅkalpā ttann abhidhyate || [16]
The target of mind is to achieve higher knowledge for enlivening the
intuition of the Jīvātmā. This presumptive mind is immortal because it has
the essence of the Ātman. The mind is related to the energy of citta.
In the Vājasaneya Saṃhita the conception of mind as a psychical entity
is fully discussed. The concept of mind is dealt with in some details in
the Vājasaneya Saṃhita and it takes the ‘mind as a whole’ i.e., tan me
manaḥ śivasaṅkal pamastu. It is not a gross physical sense organ, it cannot
be conceived as going out of the body, nor can it be the soul for the same
reason. *** Intelligence, feeling and resolution are the three-fold
divisions of mental activities and the mind is responsible for all
accomplishments. From these ideas it becomes evident that even in the
ancient texts the physical and the epistemological functions of mind have
been recognized and acknowledged.
*** The word neuron was mentioned but the intent impulses and nature were
explained. Where goes or travel the neurons? It is an electrical impulse
so, “it is not a gross physically perceivable”; atoms are travelling all
around inside and outside; but neurons are not photographed but ONLY AS AN
ENERGY; if so, energy must also flow out of bounds; but did the energy seen
outside or not? Nasadiya Suktam, hence said who knows?
The Atharvaveda uses a number of psychological *phrases like ṣardayam,
samanāsyaṃ etc. The word ‘meda’ is used for intellect or intelligence.* The
Aitareya Āraṇyaka elucidates the significance of the human mind. According
to this*, all reality exists as far as it is known.* The cognition is
divided into the knower [prājñā], the intellect [prajñā], and the cognition
[prajñānaṃ]. Some references of mind are given in the Śatapata Brāhmaṇa
about the perception and cognition of things, and the relation of name and
form with the mind. These ideas or doctrines are further elucidated in the
Aitareya Brāhmaṇa. The characteristics of mind are enumerated through a
number of concepts. Awareness, comprehension, understanding, knowledge,
retentiveness, insight, resolution, opinion, memory, reflection, impulse,
will, purposed life, desire, control etc are the names of mind or knowledge.
In the second chapter of the Aitareya Aranyaka it is mentioned that man is
superior to animals because he can anticipate the future and remember the
past. The Yajurveda states that the creations given to that in mind the
moon, in eye the sun, in ear the air and in mouth the fire are of much
significance. Mind is the first creative partner of the world.
