How specifically is the spinal cord, CNS, and PNS involved in the process of learning a new language? What function do the parasympathetic, sympathetic, autonomic, and somatic nervous systems have in learning a new language?
A large continuous area for
language learning comprehension and articulation surrounds the
lateral sulcus in the left hemisphere. The left hemisphere of the
brain is mainly involved in the language learning. There are mainly
three parts which are involved in it, which are given as
follows
1. Wernicke’s area :- it is responsible for understanding the
written and spoken language and also involved in sounding out the
unfamiliar words.
2. Broca’s area :- this area is involved in the speech
production. Broca area by a
fibre tract called the arcuate fasciculus
3. Lateral prefrontal cortex :- it
analyses the word and involved in language comprehension.
4. The lateral and ventral parts of temporal lobe :- Coordinates
the auditory and visual aspects of language (naming the objects and
reading).
The right hemisphere is also involved in body language or non
verbal communication which is also a type of language. This area
allows lilt or tone of voice and gestures to express the emotion
while speaking and permit to comprehend the emotional
content.
Spinal cord is connected to the brain via brain
stem. Spinal cord consist of vertebrae these vertebrae have the nerves specifically
sensory nerves. They carry the message to the brain via spinal cord
and helps in learning.
The PNS provides the links from the world outside our
body. White nerve thread through
virtually every part of the body enabling the CNS to receive the
information.
Parasympathetic, sympathetic,
autonomic, and somatic nervous systems are not directly involved in the new
language learning but they provide the nerves to various areas
which helps in learning the language.
Responding to the auditory feedback, recognition of sound, etc are
aided by the nerves present in Parasympathetic, sympathetic, autonomic, and
somatic nervous systems
The impulses are conducted through the
nerve cells or neurons. Neurotransmitters are the chemicals
produced at synapse which transmit signal across the neurons and
help to regulate brain mechanisms which controls language, speech,
hearing etc.
