The term area 22 of Brodmann (human) refers to a subdivision of the cytoarchitecturally defined temporal region of cerebral cortex. In the human it corresponds approximately to the lateral and caudal two thirds of the superior temporal gyrus.
1. Any limited surface or space. 2. A part of the brain or retina having a particular function. Brodmann's area's Areas of the cerebral cortex defined by Brodmann and numbered from 1 to 52.
Wernicke's area (/ˈvɛərnɪkÉ™/; German: [ˈvÉ›É̯nɪkÉ™]), also called Wernicke's speech area, is one of the two parts of the cerebral cortex that are linked to speech, the other being Broca's area.

Brodmann area 6 (BA6) part of the frontal cortex in the human brain. Situated just anterior to the primary motor cortex (BA4), it is composed of the premotor cortex and, medially, the supplementary motor area (SMA).
Broca's area and Wernicke's area are connected by a large bundle of nerve fibres called the arcuate fasciculus.
The main parts of the brain involved with memory are the amygdala, the hippocampus, the cerebellum, and the prefrontal cortex ([link]). The amygdala is involved in fear and fear memories. The hippocampus is associated with declarative and episodic memory as well as recognition memory.
The central sulcus separates the frontal lobe from the parietal lobe, and more specifically separates the primary motor cortex anteriorly from the primary somatosensory cortex posteriorly 1.
Heschl's gyrus, also known as transverse temporal gyrus, is part of the temporal lobe and contains the primary auditory cortex (Brodmann area 41). It is entirely hidden within the Sylvian fissure, with the planum temporale and superior temporal gyrus located lateral to it.
Using a microscope designed for the purpose, he undertook meticulous examinations of cortical tissue from the brains of humans and many other mammals, the results of which enabled him to construct his map of the human cortex.Using a microscope designed for the purpose, he undertook meticulous examinations of cortical tissue from the brains of humans and many other mammals, the results of which enabled him to construct his map of the human cortex. Symptoms of Broca's aphasia include:
- poor or absent grammar.
- difficulty forming complete sentences.
- omitting certain words, such as “the,†“an,†“and,†and “is†(a person with Broca's aphasia may say something like “Cup, me†instead of “I want the cupâ€)
- more difficulty using verbs than nouns correctly.
Functionally area 45 and area 44 are considered part of motor cortex, namely, the rostral part of ventral premotor cortex (PMVr in the human; F5 in the macaque) ( Matelli-2004 ). As granular prefrontal cortex, it has no equivalent in the rat ( Zilles-2012 ).
Brodmann area 44 is part of the prefrontal cortex in the human brain and is located anterior to the premotor cortex BA6 and inferior to BA9 on the lateral surface.
Broca's area is also known as the motor speech area. It is near the motor cortex and utilized in speech production, located in the inferior frontal gyrus. This area regulates breathing patterns while speaking and vocalizations required for normal speech.
Brodmann area 41 is also known as the anterior transverse temporal area 41 (H). It is a cytoarchitectonic division of the cerebral cortex occupying the anterior transverse temporal gyrus (H) in the bank of the lateral sulcus on the dorsal surface of the temporal lobe.
Broca's area is also known as the motor speech area. It is near the motor cortex and utilized in speech production, located in the inferior frontal gyrus.
It is traditionally thought to reside in Brodmann area 22, which is located in the superior temporal gyrus in the dominant cerebral hemisphere, which is the left hemisphere in about 95% of right-handed individuals and 70% of left-handed individuals.

Function. The inferior frontal gyrus has a number of functions including the processing of speech and language in Broca's area. Neural circuitry has been shown to connect different sites of stimulus to other regions of response including other subdivisions and also other frontal gyri.
The auditory cortex is the part of the temporal lobe that processes auditory information in humans and many other vertebrates. It is a part of the auditory system, performing basic and higher functions in hearing, such as possible relations to language switching.
Brodmann area 20, or BA20, is part of the temporal cortex in the human brain. The region encompasses most of the ventral temporal cortex, a region believed to play a part in high-level visual processing and recognition memory. In the human it corresponds approximately to the inferior temporal gyrus.Brodmann area 20, or BA20, is part of the temporal cortex in the human brain.

In the human it is located along the rhinal sulcus.
