Correct Answer � B
Explanation
|
|
Ans. is `b’ i.e., Cerebellum
- A feedforward control system is employed during the regulation of temperature.
- In feed-forward inhibition, a neuron is connected through two pathways one excitatory and one inhibitory.
- For example, in the cerebellum, the stimulation of Basket cells produces IPSPs (inhibitory postsynaptic potentials) in Purkinje cells.
- However, the basket cells and the Purkinje cells are excited by the same parallel-fiber excitatory input.
- This arrangement is called feed-forward inhibition and helps to prevent the duration of the excitation produced by any given afferent impulse.
