What is the diagonal band?
The diagonal band of Broca is one of the basal forebrain structures that are derived from the ventral telencephalon during development. This structure forms the medial margin of the anterior perforated substance. This brain region was described by the French neuroanatomist Paul Broca.
What is nucleus basalis?
The nucleus basalis, also known as the nucleus basalis of Meynert or nucleus basalis magnocellularis, is a group of neurons located mainly in the substantia innominata of the basal forebrain.
What is the medial septum diagonal band?
The medial septal-diagonal band of Broca (MSDB) is an important modulator of hippocampal function. The MSDB influences the hippocampus through projections from cholinergic, GABAergic, and glutamatergic neurons (Amaral and Kurz, 1985; Freund, 1989; Manseau et al., 2005).
What is basal forebrain?
The basal forebrain region is the site of a system of cholinergic neurons projecting to the entire cortical surface. The Basal Forebrain is a site of convergence of sleep and thermoregulatory functions. Portions of the basal forebrain play prominent roles in the control of the body temperature.
What are septal nuclei?
The septal nuclei are a collection of neuronal cell bodies in the rostral septum pellucidum that bulges into the medial side of the lateral ventricle.
What does substantia Innominata do?
The substantia innominata contains white matter fibers that connect the OFC to the thalamus, amygdala, and subgenual ACC. Interrupting these white matter tracts tends to modify the CSTC loops.
What does the nucleus accumbens do?
The nucleus accumbens (NAc) is a major component of the ventral striatum and has long been thought to be a key structure involved in mediating motivational and emotional processes, the limbic-motor interface, and the effects of certain psychoactive drugs.
What is prefrontal lobe?
The prefrontal cortex is a part of the brain located at the front of the frontal lobe. It is implicated in a variety of complex behaviors, including planning, and greatly contributes to personality development.
What does the septum in the heart do?
The interventricular septum separates the ventricles and allows for proper blood flow through the heart: from the right atrium through the tricuspid valve to the right ventricle to the lungs, back to the left atrium, followed by the left ventricle through the mitral valve.
