medial dorsal and lateral
the thalamic nuclei is made of unmyelinated axons which are gray matter
Thalamic Nuclei
The basal nuclei are involved in the planning and execution of movement, as well as in some aspects of cognition and emotion. They help regulate muscle tone, coordinate movements, and inhibit unwanted movements. Dysfunction of the basal nuclei can result in movement disorders such as Parkinson's disease.
The DCML- Dorsal column mediated leminiscal - system is one of the central pathways of the somatosensory system. This system is involved in mediating fine and discriminating touch. A-beta fibrers such as the Meisnerr's corpuscles, Merkel disks, Ruffinni corpuscles and Pacinian corpuscles are involved in this pathway. They are called Tactile fibres. Axons from tactile afferents ascends spinal cord and synapse on the 2nd order of the Dorsal column nuclei of the medulla. Axons of the 2nd order neurons cross to other side of brainstem and ascend to the VP (ventral posterior) complex of thalamic nuclei. The 3rd order of the thalamic nuclei project onto the primary somatosensory cortex of the mammalian brain where the information is processed. The cerebral cortex consists of 2 types of neurons- the pyramidal neurons which is excitatory; and stellate neurons which are excitatory and inhibitory. The 3rd neuron has its cell body still in the VP of the thalamic nuclei and ends in the parietal lobe- the postcentral gyrus.
All of the cerebral cortex is gray matter as it composed of neuronal cell bodies which are not insulated with myelin.
it is a beat
Sorting and editing of impulses take place in the prefrontal cortex, which is responsible for executive functions such as decision making, problem solving, and controlling impulses. Additionally, the amygdala, which is involved in emotional processing, can also play a role in filtering and modulating impulses.
loss of substantia nigra cells, as in Parkinson's disease, increases blocking of the thalamic nuclei, preventing them from sending signals to the motor cortex. The result is a loss of movement
431 is the code for intracerebral hemorrhage. That would include thalamic hemorrhage.
No, chemical reactions result only in the electrons of the atoms being involved. Only radioactivity results n nuclei of atoms being involved.
The medial nuclei of the thalamus are a group of nuclei located in the middle part of the thalamus. They play a role in processing emotions, motivation, and memory. These nuclei are involved in relaying information to and from the limbic system and the prefrontal cortex.
The protist that has two nuclei is Paramecium. It has a large macronucleus involved in regulating cellular functions and a smaller micronucleus involved in sexual reproduction.
