In this case, when Alicia is being tickled by her older sister, the divisions of the nervous system which are responsible for receiving the signals from her sister’s fingers are called somatosensory cortex and anterior cingulated cortex nervous system.
When you are touched lightly, the effect of having that ticklish sensation is caused by the analysis of two regions of the brain. For example, when our brain analyses the pressure of the touch, this is the work of the somatosensory cortex. On the other hand, as soon as something touches your skin, the signal sent from the skin's sensory receptors also passes through the anterior cingulated cortex.This is where the pleasant feelings are governed.
Answer:
The correct answer is central nervous system and peripheral nervous system.
Explanation:
The sensation of tickle stimulates the nerve terminals, the touch receptors in the skin are the constituents of the PNS. The sensation information is then transmitted via the nerve fibers to the CNS, the brain, and the spinal cord.
The assessment of information is then done in the somatosensory area of the brain, that is, in the cingulate cortex and the cerebral cortex. Thus, both the divisions of the nervous system, that is, the CNS and the PNS takes part in the process of tickling sensation.
