O Nissl stain Golgi stain Radioactive glucose stain Axonal degeneration procedure

Explanation / Answer

Temporal lobe is separated from the frontal and parietal lobes above it by a very deep indentation called the lateral fissure also called the Sylvian fissure. It is called a fissure because it is so deep that one can actually grab the lips of the lobes and separate them to see the cortex lying beneath. The brain and spinal cord are wrapped in protective membranes known collectively as the meninges.The meninges are three layers of protective tissue called the dura mater, arachnoid mater, and pia mater that surround the neuraxis. The meninges of the brain and spinal cord are continuous, being linked through the magnum foramen. The neuron doctrine states that neurons are contiguous with one another. Golgi stain provides an outline of entire neurons, including all of the cell's processes (axons and dendrites). The most common type of neuron in vertebrates is the multipolar neuron. The ventral roots of the spinal cord carry motor information to the muscles.The ventral root (motor root) of each spinal nerve consists of axons from motor neurons whose cell bodies are found within the gray matter of the spinal cord. A ventral root and a dorsal root unite to form a spinal nerve, which passes outward from the vertebral canal through an intravertebral foramen (bone opening). Stellate cell is not a type of glial cells.The glial cells surround neurons and provide support for and insulation between them. Glial cells are the most abundant cell types in the central nervous system. Types of glial cells include oligodendrocytes, astrocytes, ependymal cells, Schwann cells, microglia, and satellite cells. There are fewer glia than neurons in the CNS is false. The two cerebral hemispheres are connected by corpus callosum. TMS technique can be used to influence behaviour.Transcranial magnetic stimulation (TMS) is a noninvasive technique that allows researchers to induce electrical currents in focal areas of the cerebral cortex. These currents can transiently activate or inhibit focal cortical areas and thus influence behavior. The basal ganglia are particularly implicated in motor control. The superior colliculus is located within the midbrain.The superior colliculus refers to the rostral (front) bump on the lateral (side) part of the midbrain. It is, in fact, a pair of two colliculi, superior and inferior, on either side of the midbrain that together constitute the tectum. Caudate nucleus is specialized for motor control.The caudate nucleus is one of the structures that make up the dorsal striatum, which is a component of the basal ganglia. It plays important roles in various other nonmotor functions as well, including procedural learning, and inhibitory control of action, among other functions. Striatum is not a part of limbic system.he striatum is one of the principal components of the basal ganglia, a group of nuclei that have a variety of functions but are best known for their role in facilitating voluntary movement Oligodendrocytes is responsible for myelination within the central nervous system.. Oligodendrocyte, a type of neuroglia found in the central nervous system of invertebrates and vertebrates that functions to produce myelin, an insulating sheath on the axons of nerve fibres
