The [[dosha]] are responsible for various intellectual functions. The process of receiving-transmitting the sensory inputs and initiating motor functions is done by [[vata]] [[dosha]]. [A. Hr. Sutra Sthana 11/3] Sharpness of intelligence (medha/dhi) is attributed to [[pitta]] [[dosha]]. [A. Hr. Sutra Sthana 11/3] Maintenance of proper intellectual function is attributed to [[kapha]] [[dosha]]. [Cha. Sa. [[Sutra Sthana]] 12/12]

As per physical constitution ([[prakriti]]), individuals with [[kapha]] predominant constitution are endowed with the excellence of intelligence [A.Hr. Sharira Sthana 3/96]. The persons with [[pitta]] predominant constitution exhibit sharpness of intellectual functions. [A.Hr. Sharira Sthana 3/92]

Buddhi and medha are mentioned as the attributes of [[sattva]] [[guna]] as per the mental constitution of the person. [Su. Sa. Sharira Sthana 1/18]

A study was conducted to analyse the relation between physical and mental constitution (deha-manasa prakṛiti) and intelligence in 150 healthy individuals. It was found that intelligence quotient (IQ) was more in [[kapha]] [[prakṛti]] individuals. Moderate IQ was observed in [[pitta]] [[prakṛti]]. It was comparatively less in [[vata]] [[prakṛiti]] individuals.

Physiology of cognition in Ayurveda

===Physiology of cognition in Ayurveda===

The process of cognition is known as “jnanotpatti”. The five sensory faculties (jnanendriya) give inputs to the internal processing unit, including mind, ego, and intellect. [Cha. Sa. [[Sharira Sthana]] 1/24] The sensory signals are subjected to analysis, thought process, and generation of assumptions at the level of mind. The intellect performs the process of discrimination (adhyavasaya) and decision (nishchay). It sends signals to the motor faculty for initiation of needful action. [Cha. Sa. [[Sharira Sthana]] 1/20-23].

In the current view, cognitive functions include perception, attention, memory, learning, decision making, language abilities etc.  The process is carried out in the brain and nervous system. In perception, physical and chemical stimulation of the sensory system and transmission of signals through the nervous system to the brain occurs. Perception is influenced by the person’s learning, memory, expectation, and attention.   The perception, learning, and memory formation are explained based on the concept of synapses of neurons. The pre and post-synaptic neurons and their inter-cellular and intracellular signaling pathways are responsible for these functions. Recent studies state that the star-shaped cells called astrocytes occupy half of the brain volume. Earlier it was thought to have only structural and metabolic functions. They have a specific role in cognitive functions like learning, perception, conscious processing, and memory formation.   

 

Studies on the relation of indriya (sense and motor organs), its connection with mind and soul, its influence on functions of the brain and nervous system can provide more inputs in understanding the process of cognition.
