Hello everyone, in this question we have been asked how are interaction between the limbic system and cortex particularly interesting in humans.
00:12
So basically the structure and areas of the limbic system are involved in motivation, emotion, learning and memory and in limbic system the subcortical structure meet the cerebral cortex and the basal ganglia a set of subcortical structure that receive the input from the cerebral cortex and it sends the output to the motor centers that is present in brain stem.
00:56
So this limbic system is also connected with the prefrontal cortex and scientists believe that this connection is related to the pleasure obtained by solving problems.
01:10
So to cure the emotional disorder sometimes this connection is served due to which the patients have a lack of motivation and become passive.
01:20
So that is why it is interesting in humans.
01:28
Then we have been asked about examples of top -down cortical control of emotional states.
01:40
The top -down emotion generation is a cognition -focused view of emotional processing and the variation in the emotional response is thought to be due to differences in individual's goal states or appraisal biases.
01:55
So this elicits the activity in the amygdala as well as the dorsomedial prefrontal cortex which is thought to represent the high level of self -relevant appraisal that lead to strong subjective experience of emotion.
02:18
And this here is conscious response for how we think about our circumstances.
02:24
So like a kid gets anxious after deciding they haven't studied hard enough for an exam.
02:32
So that is a cerebral response.
02:35
So this occurs in three steps.
02:38
The stimuli occur and then the thinking pattern make us aware of what is happening.
02:44
And then there is conscious decision of what you do and then it represents how you feel.
02:55
If we see the bottom -up process, so this here deals with the lower part of the brain that is the brain stem and limbic system.
03:11
These are the parts that are responsible for light, fight, freeze or phone, memories, learning and body reflexes.
03:20
So they have mental process that occur unconsciously.
03:27
So here first of all the stimuli occur and then an emotion is sparked.
03:33
So the bottom -up approach admits that body sensation or feelings are the first to occur.
03:39
So the major benefit of a bottom -up approach is that it integrates the entire brain.
03:45
Then we have been asked that what are the ways in which synaptic function can change in response to experience.
03:53
So basically the ability of synapses to change or remodel themselves is called as synaptic plasticity.
04:04
And encoding a new long -term memory involves the persistent changes in the number and shape of synapses as well as the number of chemical messages that is sent and the molecular docking stations or receptors available to receive the message...
