What is nucleus Reuniens?
The nucleus reuniens (RE) is a ventral midline thalamic nucleus that interconnects the medial prefrontal cortex (mPFC) and hippocampus (HPC).
What does the medial nuclei of the thalamus do?
The medial dorsal nucleus (or dorsomedial nucleus of thalamus) is a large nucleus in the thalamus. It receives inputs from the Pre-Frontal Cortex and the Limbic System and in turn relays them to the Pre-Frontal Association Cortex.
Where is the nucleus reuniens?
The nucleus reuniens is a component of the thalamic midline nuclear group. In the human brain, it is located in the interthalamic adhesion (massa intermedia). The nucleus reuniens receives afferent input from a large number of structures, mainly from limbic and limbic-associated structures.
What is the function of the thalamus with regards to memory?
Connections to structures such as the hippocampus and other parts of the limbic system suggest the thalamus plays a role in memory, especially episodic memory, as well as with learning and emotions. The thalamus is also believed to be involved in the regulation of sleep, wakefulness, and arousal.
Which nucleus of the thalamus has projections with the hippocampus?
thalamic nucleus reuniens
The thalamic nucleus reuniens (RE) receives dense projections from the medial prefrontal cortex (mPFC), interconnects the mPFC and hippocampus, and may serve a pivotal role in regulating emotional learning and memory.
What is the function of the thalamus in psychology?
The thalamus (from the Greek word meaning “chamber”) is centrally located between the cerebral cortex and the midbrain and is known for its role in relaying sensory and motor signals to the cerebral cortex, and the regulation of sleep, consciousness, and alertness—rather like a hub of information flow from the senses …
Is the thalamus connected to the hippocampus?
Thalamus and hippocampus have connections with a large number of cortical and subcortical brain regions (eg, the anterior thalamic nuclei connect with the prefrontal and orbitofrontal cortex and cingulate gyrus).
Does hippocampus project to thalamus?
1 that the hippocampus projects both directly and indirectly to the anterior thalamic nuclei as the mammillary bodies innervate the anterior thalamic nucleus via the mammillothalamic tract.
What does the thalamus do simple explanation?
The thalamus relays sensory impulses from receptors in various parts of the body to the cerebral cortex. A sensory impulse travels from the body surface towards the thalamus, which receives it as a sensation. This sensation is then passed onto the cerebral cortex for interpretation as touch, pain or temperature.
