What is the process in which certain cognitive functions are located more in one hemisphere of the brain than in the other?.
yKpoI14uk [10]

Hemispheric lateralization is the process in which certain cognitive functions are located more in one hemisphere of the brain than in the other.

The concept of hemispheric lateralization holds that both hemispheres have distinct functional roles and that some mental functions and behaviors are primarily governed by one hemisphere as opposed to the other. There is evidence of some functional specialization, particularly with regard to variations in language skills.

The left and right sides of the brain have different capacities for regulating different forms of motor action, focusing on different kinds of information, and processing sensory inputs in different ways. This is referred to as hemisphere specialization or brain lateralization.

A nerve poison that blocks acetylcholine receptors on dendrites would _____. a nerve poison that blocks acetylcholine receptors
nata0808 [166]
Nerve poisons, or nerve gases are organic chemicals that interfere with the mechanism by which nerves transfer messages to organs. The interference is as a result of the blocking of acetylcholinesterase, and enzyme that catalyzes the breakdown of acetycholine, a neurotransmitter. Therefore, a poison that blocks acetylcholine receptors on dendrites may reduce or decrease the binding of acetycholine to its receptors on the postsynaptic membrane.
