The term hippocampal formation typically refers to the dentate gyrus, the hippocampus proper (i.e., cornu ammonis), and the subicular cortex.

A Tour of the Brain The midbrain — the uppermost part — has fibers that connect the brain stem to the cerebrum and cerebellum; this area is very important in the control of skeletal movements. The pons, which lies between the midbrain and medulla oblongata, relays sensory information between the cerebrum and cerebellum.

An Overview of the Brain It is made of three parts: the midbrain, pons, and medulla oblongata. 1  The midbrain is located between the pons and the cerebral hemispheres. 2  The pons sends messages between the cerebrum and cerebellum and the spinal cord. 3  The medulla oblongata connects the brain with the spinal cord.

- [edit on Wikidata] The midbrain or mesencephalon (from the Greek mesos, middle, and enkephalos, brain) is a portion of the central nervous system associated with vision, hearing, motor control, sleep/wake, arousal (alertness), and temperature regulation.

- The medial forebrain bundle contains a number of powerful pathways connecting one end of the forebrain to the hindbrain. These pathways allow the forebrain and limbic system to modulate both somatic and visceral activity and provide routes whereby the internal organs and bodily actions can influence the activity of higher brain functions.

- Related areas. Besides the hypothalamus, hippocampus, and amygdala, there are other areas in the structures near to the limbic system that are intimately connected to it: The cingulate gyrus is the part of the cerebrum that lies closest to the limbic system, just above the corpus collosum. It provides a pathway from the thalamus to the hippocampus, seems to be responsible for focusing attention on emotionally significant events, and for associating memories to smells and to pain.

Divisions of the Brain The hindbrain is composed of two subregions called the metencephalon and myelencephalon. Several cranial nerves are located in this brain region. The trigeminal, abducent, facial, and vestibulocochlear nerves are found in the metencephalon. The glossopharyngeal, vagus, accessory, and hypoglossal nerves are located in the myelencephalon. The fourth cerebral ventricle also extends through this region of the brain. The hindbrain assists in the regulation of autonomic functions, maintaining balance and equilibrium, movement coordination, and the relay of sensory information.

Brainstem: Its Function and Location The brainstem is composed of the midbrain and portions of the hindbrain, specifically the pons and medulla. A major function of the midbrain is to connect the three major brain divisions: forebrain, midbrain, and hindbrain. Major structures of the midbrain include the tectum and cerebral peduncle. The tectum is composed of rounded bulges of brain matter that are involved in visual and auditory reflexes.

The Architecture of the Brain First let's divide the brain into three basic units: the Forebrain, the Midbrain, and the Hindbrain (shown below). The hindbrain includes the upper part of the spinal cord, the brain stem, and a wrinkled ball of tissue called the Cerebellum. The uppermost part of the brainstem is the midbrain. The forebrain is the largest and most highly developed part of the human brain: it consists primarily of the Cerebrum and the structures hidden beneath it. When people see pictures of the brain it is usually the cerebrum that they notice. The cerebrum sits at the topmost part of the brain.

Limbic system The limbic system (or paleomammalian brain) is a complex set of brain structures located on both sides of the thalamus, right under the cerebrum. It is not a separate system but a collection of structures from the telencephalon, diencephalon, and mesencephalon.

- Midbrain. The midbrain, also called the mesencephalon, is a small region of the brain that serves as a relay center for visual, auditory, and motor system information. It regulates autonomic functions, those that the body carries out without conscious thought, such as digestion, heart rate, and breathing rate.halamus. The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. It works to correlate several important processes, including consciousness, sleep, and sensory interpretation.

Brain structure Forebrain. The forebrain consists of the cerebral cortex, the basal ganglia, the limbic system, the thalamus, and the hypothalamus. The cerebral cortex is the outer layer of the brain and is just a few millimetres thick. It is involved in memory, attention, language, thinking, and voluntary movement.

- The brain is made of three main parts: the forebrain, midbrain, and hindbrain. The forebrain consists of the cerebrum, thalamus, and hypothalamus (part of the limbic system). The midbrain consists of the tectum and tegmentum. The hindbrain is made of the cerebellum, pons and medulla.Often the midbrain, pons, and medulla are referred to together as the brainstem. The Cerebrum: The cerebrum or cortex is the largest part of the human brain, associated with higher brain function such as thought and action.he brain is made of three main parts: the forebrain, midbrain, and hindbrain.

Midbrain The midbrain comprises the tectum, tegmentum, the cerebral aqueduct, and the cerebral peduncles, as well as several nuclei and fasciculi. Caudally the midbrain adjoins the metencephalon (afterbrain) (pons and cerebellum); while rostrally it adjoins the diencephalon (thalamus, hypothalamus, etc.) Specifically, the midbrain consists of: Tectum

Midbrain ...the shape of the lens and the diameter of the pupil. In addition, between the midbrain reticular formation (known here as the tegmentum) and the crus cerebri is a large pigmented nucleus called the substantia nigra. The substantia nigra consists of two parts, the pars reticulata and the pars compacta. Cells of the pars compacta contain the dark pigment melanin; these cells synthesize dopamine and project to either the caudate nucleus or the putamen.

The HOPES Brain Tutorial (Text Version) The limbic system contains many parts, including the cingulate gyrus, a band of cortex that runs from the front of the brain to the back, the parahippocampal gyrus, the dentate gyrus, and most notably, the hippocampus and amygdala. The hippocampus is involved in memory storage and formation.

- The limbic system is the forebrain area next to the brainstem that includes a number of interdependent structures under the cerebral cortex, which deal with motivation and are critical in regulating emotions, sexual activity, eating, drinking, anxiety and aggression (Kalat J., 2003).

- Several important nuclei are located in the midbrain, including the red nuclei, the substantia nigra, and the nuclei of cranial nerves III and IV. The red nuclei connect the midbrain to the cerebellum and to the inner ear. It is also an important part of the extra pyramidal tract.he corpora quadrigemina, which is located on the posterior surface of the midbrain, is composed of two superior colliculi and two inferior colliculi. The superior colliculi are part of the visual system, relaying input from the optic tract to the lateral geniculate bodies of the thalamus.

Hindbrain Cerebellum: Cerebellum is the second largest part of brain (after cerebrum). It lies within the posterior cranial fossa beneath the tentorium cerebelli. Its position in the hindbrain is posterior to both pons and medulla oblongata.It is connected to the midbrain through superior cerebellar peduncles, to the pons through middle cerebellar peduncles and to the medulla through inferior cerebellar peduncles.ons is situated below the midbrain and above the medulla oblongata anterior to the cerebellum. It is mainly composed of those nerve fibers that connect the two halves of cerebellum. In addition, it also contains the ascending and descending fibers connecting the forebrain, midbrain and the spinal cord.

Midbrain tegmentum Midbrain tegmentum. The midbrain is also known as the Mesencephalon and is one of the three major brain divisions. The midbrain is broken up into the tectum and the tegmentum. There are some important structures located within the tegmentum. The midbrain tegmentum is the part of the midbrain extending from the substantia nigra to the cerebral aqueduct in a horizontal section of the midbrain. It forms the floor of the midbrain that surrounds the cerebral aqueduct.

Basic Parts of the Brain and Their Responsibilities The brainstem consists of the midbrain and the hindbrain. Just as the name suggests, the brainstem resembles the stem of a branch. The midbrain is the upper part of the branch that is connected to the forebrain. This region of the brain sends and receives information. Data from our senses, such as the eyes and ears, are sent to this area and then directed to the forebrain.
