Study Notes
Structure of the Cerebrum
- The cerebrum is the top part of the brain, composed of grey and white matter.
- The entire cerebrum is covered with grey matter, known as the cerebral cortex.
- The deep structures, including white matter and grey matter nuclei, are called subcortical because they are beneath the cerebral cortex.
Subcortical White Matter
- The cerebral hemispheric white matter contains myelinated axons projecting to or from the cerebral cortex and to and from subcortical structures like grey nuclei deep in the cerebrum and/or to and from the brainstem.
- One important subcortical white matter structure deep in the cerebrum is the internal capsule.
- The internal capsule contains a number of important pathways for information traveling around the central nervous system, including the corticospinal tract that contains upper motor neurons.
- The internal capsule separates some subcortical grey matter nuclei and appears as a V-shaped structure in top-down views.
Connections between Cerebral Hemispheres
- Several white matter structures connect the two cerebral hemispheres.
- The largest and most important connection is the corpus callosum, a big band of white matter that allows information to travel from one cerebral hemisphere to the other.
Basal Ganglia
- The basal ganglia are several subcortical nuclei that function as a unit.
- They play a major role in motor functions, helping out motor areas of the cerebral cortex to perform proper movements.
- They also contribute to cognition and emotion.
Thalamus
- The thalamus is a group of subcortical nuclei that play a very important role in sensory functions, with almost all senses having pathways that travel to the thalamus for sensory processing.
- The thalamus is also important for higher functions of the brain, including cognition, emotion, and consciousness, due to its connections to many brain areas.
Hypothalamus
- The hypothalamus is a group of nuclei below the thalamus, connected to and controlling the pituitary gland, the master gland that regulates the endocrine system.
- The hypothalamus plays a major role in controlling and interacting with the endocrine system, and is the link between the nervous system and the endocrine system.
- It is also connected to many brain areas and plays a role in higher functions of the brain, including cognition, emotion, and consciousness.
Structure of the Cerebrum
- Composed of grey and white matter, with grey matter (cerebral cortex) covering the entire cerebrum.
- Subcortical structures include white matter and grey matter nuclei, located beneath the cerebral cortex.
Subcortical White Matter
- Cerebral hemispheric white matter contains myelinated axons projecting to/from the cerebral cortex and subcortical structures.
- Internal capsule is a significant subcortical white matter structure, containing important pathways for information traveling around the CNS.
- Internal capsule separates subcortical grey matter nuclei and appears as a V-shaped structure in top-down views.
Connections between Cerebral Hemispheres
- Several white matter structures connect the two cerebral hemispheres, including the corpus callosum.
- Corpus callosum is a large band of white matter, allowing information to travel between the two hemispheres.
Basal Ganglia
- A group of subcortical nuclei that function as a unit.
- Play a major role in motor functions, assisting motor areas of the cerebral cortex.
- Contribute to cognition and emotion.
Thalamus
- A group of subcortical nuclei that play a crucial role in sensory functions.
- Almost all senses have pathways that travel to the thalamus for sensory processing.
- Important for higher functions of the brain, including cognition, emotion, and consciousness.
Hypothalamus
- A group of nuclei below the thalamus, connected to and controlling the pituitary gland.
- Plays a major role in controlling and interacting with the endocrine system.
- Link between the nervous system and the endocrine system.
- Connected to many brain areas, influencing cognition, emotion, and consciousness.
