Apr 26, 2024 · The ventral tegmental area (VTA) is a heterogeneous brain region, containing different neuronal populations. During recordings, electrophysiological characteristics are classically used to distinguish the different populations. However, the VTA is also considered as a region harboring neurons with heterogeneous properties.
2 days ago · Alcohol dependence activates ventral tegmental area projections to central amygdala in male mice and rats. Addiction Biology, doi: 10.1111/(ISSN)1369-1600. Weera MM, Schreiber AL, Avegno EM, Gilpin NW (2020). The role of central amygdala corticotropin-releasing factor in predator odor stress-induced avoidance behavior and escalated alcohol ...
Apr 24, 2024 · Mesocortical Pathway: The mesocortical dopamine pathway carries dopamine from the ventral tegmental area (VTA) to various areas within the prefrontal cortex. Neurons in the VTA and The dopaminergic projections within this pathway assist the prefrontal cortex in sustaining cognition and working memory and can cause more efficacious decision-making.
May 2, 2024 · The medulla oblongata plays a critical role in transmitting signals between the spinal cord and the higher parts of the brain and in controlling autonomic activities, such as heartbeat and respiration. Medial view of the left hemisphere of the human brain. The medulla is divided into two main parts: the ventral medulla (the frontal portion) and ...
2 days ago · The causes could be biological factors, such as a lack of dopamine from the nucleus accumbens (located in the ventral striatum), which affects how the brain processes a reward. Additionally, dopamine-related problems could occur with the ventral tegmental area. Another issue could be problems in the ventral pallidum.
Apr 30, 2024 · Despite its theoretical importance, it remains unknown whether a neuronal implementation of this algorithm exists in the brain. Here, we provide an interpretation of the recently described signaling properties of ventral tegmental area (VTA) GABAergic neurons and show that a circuitry of these neurons implements the TDL algorithm.
Widely projecting DA neurons have their cell bodies in the midbrain, within the substantia nigra pars compacta and the ventral tegmental area. DA is also produced by neurons in the arcuate nucleus of the hypothalamus, and by local circuit neurons in the retina.
