It consists of many nuclei, each made up of further subnuclei. The subdivision most commonly made is into the basolateral, central, cortical, and medial nuclei together with the intercalated cell clusters. [4] The amygdala has a primary role in the processing of memory, decision-making, and emotional responses (including fear, anxiety, and ...
Ganglia provide relay points and intermediary connections between different neurological structures in the body, such as the peripheral and central nervous systems. Among vertebrates there are three major groups of ganglia: Dorsal root ganglia (also known as the spinal ganglia) contain the cell bodies of sensory (afferent) neurons.
The regions described as amygdala nuclei encompass several structures with distinct connectional and functional characteristics in humans and other animals. [9] Among these nuclei are the basolateral complex, the cortical nucleus, the medial nucleus, and the central nucleus. The basolateral complex can be further subdivided into the lateral ...
The difference between resting and cognitive paradigms may be due to increased signal to noise ratio, a possible mechanism of aberrant valuation. OFC-striatum connectivity also predicts symptom severity, although the opposite has been found in some studies.
The basal ganglia are a set of subcortical structures that direct intentional movements. The basal ganglia are located near the thalamus and hypothalamus. They receive input from the cerebral cortex, which sends outputs to the motor centers in the brain stem. A part of the basal ganglia called the striatum controls posture and movement.
Basal ganglia: striatum (caudate and putamen), pallidum (globus pallidus, medial and lateral), substantia nigra, subthalamic nucleus; Cranial nerve nuclei; Ventromedial nucleus of the hypothalamus: "The ventromedial hypothalamus (VMH) is a distinct morphological nucleus involved in feeding, fear, thermoregulation, and sexual activity."
The basal ganglia (BG) or basal nuclei are a group of subcortical nuclei found in the brains of vertebrates. In humans and other primates , differences exist, primarily in the division of the globus pallidus into external and internal regions, and in the division of the striatum .
Anxiety can be experienced with long, drawn-out daily symptoms that reduce quality of life, known as chronic (or generalized) anxiety, or it can be experienced in short spurts with sporadic, stressful panic attacks, known as acute anxiety. [23] Symptoms of anxiety can range in number, intensity, and frequency, depending on the person.
