The telencephalon has four major components: the cerebral cortex, the limbic forebrain structures, the basal ganglia, and the olfactory system . The diencephalon consists of two major structures: the thalamus and hypothalamus and two smaller structures, the epithalamus
What is telencephalon made of?
The telencephalon is composed of surface grey matter (the cerebral cortex) and underlying white matter, with deep masses of grey matter 2 . The corpus callosum facilitates communication between the two hemispheres 3 .
What lobes are in the telencephalon?
The 6 major lobes comprise the frontal lobe, parietal lobe, temporal lobe, occipital lobe, insular lobe, and limbic lobe . In addition, each hemisphere has 3 surfaces and 2 borders.
Which structure is not part of the telencephalon?
The cerebellum (unlabeled) is not part of the telencephalon. Diagram depicting the main subdivisions of the embryonic vertebrate brain.
Is the hippocampus in the telencephalon?
In addition to the cortex and its recognizable features, there are a large number of subcortical structures that are considered part of the telencephalon . These include the hippocampus, amygdala, and a majority of the regions included in the basal ganglia, among others.
Is telencephalon the same as forebrain?
Forebrain, also called prosencephalon , region of the developing vertebrate brain; it includes the telencephalon, which contains the cerebral hemispheres, and, under these, the diencephalon, which contains the thalamus, hypothalamus, epithalamus, and subthalamus.
What is the main function of the telencephalon?
Movement. The telencephalon is the part of the brain which attributes motor function to the body. These functions originate within the primary motor cortex and other frontal lobe motor area.
Is the frontal lobe in the telencephalon?
Parts of the telencephalon
Frontal lobe – The frontal lobe is associated with personality, conscience (right/wrong/consequences), planning and is the source of inhibitions. ... Occipital lobe – The occipital lobe processes visual memory, and is associated with migraine headaches.
Is the corpus callosum part of the nervous system?
Corpus callosum, bundle of nerve fibres in the longitudinal fissure of the brain that enables corresponding regions of the left and right cerebral hemispheres to communicate. ... In addition, agenesis (imperfect development) of the corpus callosum can cause intellectual disability and seizures.
What does telencephalon refer to?
also known as the cerebrum, the telencephalon refers to the region of the brain that includes the cerebral cortex and several subcortical structures including the hippocampus and basal ganglia .
What connects the two hemispheres of the brain?
The two hemispheres are connected by a thick band of nerve fibres called the corpus callosum . The brain halves are able to communicate with each other via this ‘bridge’.
What is corpus callosum?
The corpus callosum is the primary commissural region of the brain consisting of white matter tracts that connect the left and right cerebral hemispheres.
Is the diencephalon white or GREY matter?
It is located behind and below the cerebrum and at the back of the brain stem and attached to the midbrain. It has two hemispheres and an outer cortex of gray matter and an inner core of white matter. ... The diencephalon is located between the cerebrum and midbrain.
What is the function of the corpus callosum?
The two hemispheres in your brain are connected by a thick bundle of nerve fibres called the corpus callosum that ensures both sides of the brain can communicate and send signals to each other .
What part of the brain is the seat of intelligence?
The part of the brain in which the seat of intelligence is located is the frontal lobe .
What is the epithalamus?
The epithalamus is a small region of the diencephalon consisting of the pineal gland, habenular nuclei, and stria medullaris thalami . The pineal gland contains no true neurons, only glial cells. ... The stria medullaris connects fibers from the habenular nuclei with the limbic system.
