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 ...
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.
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.
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 – Basal ganglia are groups of nuclei found on either side of the thalamus. Basal ganglia play an important role in motivation, [26] action selection and reward learning. [27] Orbitofrontal cortex – The orbitofrontal cortex is involved in decision making and helping us understand how emotions have influenced our decision making ...
The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain and spinal cord.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
The ganglia above the gut are the cerebral, the pleural, and the visceral, which are located above the esophagus (gullet). The pedal ganglia, which control the foot, are below the esophagus and their commissure and connectives to the cerebral and pleural ganglia surround the esophagus in a circumesophageal nerve ring or nerve collar.
