Solution
Q.Which neural circuitry is involved in regulating the executive function and decision-making?
Answer-prefrontal cortex (PFC)
Description-The dorsolateral prefrontal cortex is an area in the prefrontal cortex of the brain.An important function of the dorsolateral prefrontal cortex is the executive functions, such as working memory, cognitive flexibility.
34. Which neural circuitry is involved in regulating the autonomic response especially in chronic stress responses that often leads to the shutting down of both the CNS, the periphery and the immune system?
Answer-hypothalamic-pituitary-adrenal circuitry
Description-The autonomic nervous system and hypothalamic-pituitary-adrenal axis are major systems that respond to stress. the HPA axis regulates the release of cortisol, which influences many bodily functions such as metabolic, psychological and immunological functions.
36. What is the evolutionary older emotional circuitry of the subcortical inner loop that involves cingulate cortex, hippocampus, mammillary body of the hypothalamus and anterior thalamic nucleus call?
Answer- E) Pepez circuit for emotions
Description-Initially believed that the circuit was involved with emotion. The circuit connects the hypothalamus and the cortex and acts as the emotional system of the brain. The cingulate cortex projects to the hippocampus, and the hippocampus projects to the hypothalamus by way of the bundle of axons called the fornix. Hypothalamic effects reach the cortex via a relay in the anterior thalamic nuclei.However, there has not been additional proof of the circuit\'s role in emotion over the years. Now, the Amygdala is thought to play a key role in emotion
38. Which part of the brain is involved in integrating the different senses together to form a coherent sense of self?
Answer-B. prefrontal cortex
Description- In brain important area for retrieving self-knowledge are the medial prefrontal cortex and the medial posterior parietal cortex
39.Which brain pathway is involved in regulation the perception of emotional pain vs. physical pain?
Answer-amygdala
Description-Pain having a strong affective and emotional dimension, signal-regulated kinase in the amygdala modulates pain perception.
40. Which circuitry is involved in the sensory perception of body parts?
Answer-somatosensory cortex
Description-The somatosensory cortex receives all sensory input from the body.
