The medial septal nuclei are located in the anteroventral cerebrum. They have reciprocal connections to other parts of the limbic system; the hippocampus, amygdala, hypothalamus, cingulate gyrus, and thalamus. They are also connected to the midbrain. What we know most about the medial septal nuclei is that they play an important role in reward and reinforcement.
So, if the medial septal nuclei where stimulated, the brain would perceive a reward, a pleasurable sensation.
What else can I help you with?
What does the posterior nuclei of the thalamus consist of?
lateral and medial geniculate nuclei
Which thalamic nuclei are involved in emotion?
medial dorsal and lateral
What is the medial nuclei of the thalamus?
It depends on which group of thalamic nuclei that you are referring to.anterior group of nuclei = relay station for hippocampal impulsesmedial group of nuclei = relay station for visceral impulsesanterior ventral group of nuclei = relay station for extrapyramidal impulsesintermediate ventral group of nuclei = relay station for cerebellar impulses concerned with integration of muscle tonepostero-lateral ventral group of nuclei = relay station for exteroceptive impulses & proprioceptive impulses from the opposite side of the body below the headpostero-medial ventral group of nuclei = relay station for exteroceptive and proprioceptive impulses from opposite side of headinterlaminar + midline + reticular nuclei = participate in the arousal reactions of the brain
What is the medial longitudinal fasciculus?
The medial longitudinal fasciculus is a neural pathway in the brainstem that connects the nuclei responsible for eye movements. This pathway allows for coordinated movements of the eyes, particularly in response to visual stimuli. Dysfunction of the medial longitudinal fasciculus can result in conditions such as internuclear ophthalmoplegia.
What is the granular appearing cytoplasm more apparent at the sides of a cell rather than in the middle?
because sometimes the nuclei is above the cytoplasm because the nuclei is in the middle. It can also be because the sides are where there is the most activity.
What are the four parts of the hypothalamus?
optic part, which contains 2 nuclei = supraoptic + paraventricular nucleituberal part, has 3 nuclei = ventromedial + dorsomedial + tubral nucleimamillary part, has 2 nuclei = posterior + lateral nucleiposterior perforated substance
What is the origin of medial corticobulbar fibers?
The medial corticobulbar fibers originate from the primary motor cortex (M1) in the precentral gyrus of the brain. These fibers are part of the corticobulbar tract, which is responsible for carrying motor signals from the cerebral cortex to the brainstem nuclei that control the muscles of the face, head, and neck.
What are the five nuclear groups of thalamus?
medial groupanterior grouplateral group, subdivided into = dorsal lateral + postero-lateral nucleiventral group, subdivided into = anterior ventral + imtermediate ventral + posterior ventral nucleinon-specific nuclei, which include = intralaminar + reticular + middle line nuclei
How do you calculate the activity of a radioactive sample?
The activity of a radioactive sample is calculated using the formula: Activity = λ*N, where λ is the decay constant of the isotope and N is the number of radioactive nuclei present in the sample. The unit of activity is becquerel (Bq).
What are the nuclei of the grey matter of spinal cord?
nuclei of the posterior horn (sensory) = substantia gelatinosa of Rolandi + Nucleus proprius + Clark's dorsal nucleusnuclei of the anterior horn (motor) = 2 medial + 1 central + 2 lateral groupsnuclei of the lateral horn (autonomic) = sympathetic (T1-L2/L3) + parasympathetic (S2-S4)
Is the cerebellum and basal nuclei involved in regulating motor activity and coordinating postural movements?
Yes, both the cerebellum and basal nuclei are involved in regulating motor activity and coordinating postural movements. The cerebellum helps in smooth coordination and precision of movements, while the basal nuclei assist in initiating and inhibiting movements to maintain posture and balance. Together, they play crucial roles in controlling voluntary movements and maintaining stability.
What are the two main parts of pons?
Basilar (ventral/anterior) part, which contains =pontine nuclei + transverse fibres + longitudinal fibres (pyramidal tracts and corticopontine fibres)Tegmental (dorsal/posterior) part, which contains = nuclei of the middle four cranial nerves (trigeminal, abducen, facial and vestibulocochlear nerves) + 4 Lemnisci (lateral, spinal, trigeminal and medial)
