Hello everyone, in this question we have been asked that which of the following structure is necessary for the procedural memory.
00:10
So here if we talk about the option a that is inferotemporal cortex, this here is a key part of the ventral visual pathway that is implicated in object face and scene perception and it is located on the lower portion of outer layer of the temporal lobe and then we have the striatum which is the largest structure of the basal ganglia and the striatum is divided into a ventral and a dorsal subdivision.
00:54
It is composed of the nucleus and accumbens and the olfactory tubercle.
01:00
Functionally the striatum coordinates the multiple aspects of cognition including both the motor and action planning, decision making, motivation, reinforcement and reward perception.
01:19
Then we have the hippocampus.
01:22
The hippocampus is the complex brain structure embedded deep into the temporal lobe and it has a major role in learning as well as in memory.
01:35
Then the next option we have is the pararenal cortex.
01:41
This plays a role in object recognition memory.
01:47
So the part of the brain that plays important role in the procedural memory is the cerebellum.
01:57
So here we need to know that which of these structure belongs to cerebellum is the option b.
02:04
So option b will be our right answer.
02:07
Then next option, then next question says that people with huntington's disease and parkinson's disease show a procedural memory deficit.
02:16
So basically the patients having the huntington's disease have the associated deficit in the procedural learning that is consistent with the hypothesis that the striatum plays a critical role in supporting procedural learning.
02:32
So this here is a true statement.
02:35
So here our right answer will be option a that is this statement is true.
02:40
Now in the next question, we have been asked that the prefrontal cortex receives the afferent from the striatum and cerebellum implicating this area of cortex in procedural memory.
02:58
So basically the prefrontal cortical areas that are the ac, the trl, the il and ofc are interconnected and these receive the afferents from the somatosensory and motor cortical cells.
03:21
So this can be regarded to be the region of cortex that receives the principal thalamic inputs from the mediodorsal nucleus of the thalamus and these receive massive inputs from the sensory association cortices that are the somatosensory, visual and auditory and also from the dorsomedial nucleus of the thalamus.
03:46
So this here is incorrect...
