How does dopamine affect hippocampus?
The dopaminergic neurons projecting from the ventral tegmental area (VTA) to the ventral hippocampus have been hypothesized to be part of a functional loop through which dopamine signals novelty and strengthens memory consolidation in the hippocampus (Lisman and Grace, 2005).
Does the hippocampus use dopamine?
Accumulating evidence indicates that dopamine has an important role in hippocampus-dependent learning and memory (for review see Lisman & Otmakhova, 2001). Indeed, the hippocampus receives dopamine projections from the ventral tegmental area (VTA) and the substantia nigra pars compacta (SNc) (Bischoff et al.
Which disease is associated with dysregulation of the dopamine and serotonergic system decreased gray matter abnormal cortical thinning and abnormal migration of hippocampal neurons?
Moreover, we propose that the hippocampal dysfunction consistently observed in schizophrenia patients is the basis for the dopamine dysregulation in this disorder.
What is dopamine Journal?
Dopamine (DA) plays a vital role in reward and movement regulation in the brain. In the reward pathway, the production of DA takes place in the ventral tegmental area (VTA), in nerve cell bodies. From there, it is released into the nucleus accumbens and prefrontal cortex.
How are dopamine neurons in the midbrain diverse?
Midbrain dopamine (DA) neurons have diverse functions that can in part be explained by their heterogeneity. Although molecularly distinct subtypes of DA neurons have been identified by single-cell gene expression profiling, fundamental features such as their projection patterns have not been elucidated.
Is the hippocampus part of the prefrontal cortex?
In rodents, the hippocampus has been studied extensively as part of a brain system responsible for learning and memory, and the prefrontal cortex (PFC) participates in numerous cognitive functions including working memory, flexibility, decision making, and rewarding learning.
What are the interactions between the PFC and the hippocampus?
Interactions between the hippocampus and the PFC are of major interest in understanding the neurobiology of psychiatric and neurodegenerative disorders. There are both direct- and indirect-Hip-PFC pathways.
What are the postsynaptic potentials in the hippocampus?
Single pulse stimulation in the hippocampus evoked early excitatory postsynaptic potentials (EPSPs) and later inhibitory postsynaptic potentials (IPSCs) in pyramidal cells of PFC [ 11 E. Dégenètais, A.-M. Thierry, J. Glowinski, and Y. Gioanni]
