Later, in a pair of 1942 publications, Harald Brockhaus referred to the cells as the basal nucleus {Basalkern}). [14] [15] In these reports, he also emphasized the continuity of the nucleus basalis proper with the nucleus of the diagonal band of Broca, referring to the entire collection of large cells as the basal nucleus complex ...
The term "basal" comes from the fact that most of its elements are located in the basal part of the forebrain. The term ganglia is a misnomer: In modern usage, neural clusters are called "ganglia" only in the peripheral nervous system ; in the central nervous system they are called "nuclei".
Stimulating the basal forebrain gives rise to acetylcholine release, which induces wakefulness and REM sleep, whereas inhibition of acetylcholine release in the basal forebrain by adenosine causes slow wave sleep. The nucleus basalis is the main neuromodulator of the basal forebrain and gives widespread cholinergic projections to the neocortex.
The basal ganglia, also called basal nuclei, are a set of structures deep within the hemispheres involved in behaviour and movement regulation. [28] The largest component is the striatum , others are the globus pallidus , the substantia nigra and the subthalamic nucleus . [ 28 ]
Location: The shell is the outer region of the nucleus accumbens, and – unlike the core – is considered to be part of the extended amygdala, located at its rostral pole. Cell types: Neurons in the nucleus accumbens are mostly medium spiny neurons (MSNs) containing mainly D1-type (i.e., DRD1 and DRD5 ) or D2-type (i.e., DRD2 , DRD3 , and ...
Location of the human cerebrum (red). The cerebrum is the largest part of the brain. Depending upon the position of the animal, it lies either in front or on top of the brainstem. In humans, the cerebrum is the largest and best-developed of the five major divisions of the brain.
The basal ganglia are located bilaterally, and have rostral and caudal divisions. The putamen is located in the rostral division as part of the striatum. The basal ganglia receive input from the cerebral cortex, via the striatum. This is a transverse section of the striatum from a structural MR image.
The basolateral amygdala, or basolateral complex, or basolateral nuclear complex consists of the lateral, basal and accessory-basal nuclei of the amygdala. [1] The lateral nuclei receives the majority of sensory information, which arrives directly from the temporal lobe structures, including the hippocampus and primary auditory cortex.
