<u>Answer:</u>
The typical state of a neuron is the<u> resting potential</u>, but when electrical signals stimulate it to its threshold, the <u>action potential</u> is immediately observed.
<u>Explanation:</u>
The capacity for rest shows what occurs when a neuron is at rest. A capacity for action takes place when a neuron passes information down an axon, far from the cell body. When depolarization exceeds approximately -55 mV a neuron can activate the capacity for action.
Sodium-potassium valves start moving two potassium ions within the cell as three sodium ions are poured out to keep the negatively charged membrane within the cell; this keeps the resting potential in place.
The Brodmann areas are a method of mapping the cortex and its distinct functions that was developed by Korbinian Brodmann, after whom the areas are named.
Korbinian Brodmann (November 17, 1868 – August 22, 1918) was a German neurologist best known for classifying the cerebral cortex into 52 distinct regions based on cytoarchitectonic (histological) characteristics. These areas are now commonly known as Brodmann areas.
The Brodmann classification divides the cortex into approximately 52 sequentially numbered areas, though some regions have since been subdivided and others are only found in non-human primates.
It is in charge of motor movements such as contralateral finger/hand/wrist or orofacial movements, learned motor sequences, breathing control, and voluntary blinking. The primary visual cortex (Brodmann area 17) is located on the medial surface of the occipital lobe, in and on either side of the calcarine sulcus.
