In the anatomy of the brain of vertebrates, the forebrain or prosencephalon is the rostral (forward-most) portion of the brain. TEACHING POINTS The midbrain connects the pons and cerebellum with the forebrain and can be divided into a ventral part, the tegmen-tum, and a dorsal part, the tectal or quadrigeminal plate.[1] The brain is an organ composed of nervous tissue that commands task-evoked responses, movement, senses, emotions, language, communication, thinking, and memory. Mesencephalon. The subarachnoid cisterns, or basal cisterns , are compartments within the subarachnoid space where the pia mater and arachnoid membrane are not in close approximation and cerebrospinal fluid (CSF) forms pools or cisterns (Latin: "box"). [ edit on Wikidata] The metencephalon is the embryonic part of the hindbrain that differentiates into the pons and the cerebellum.. The brain integrates sensory information and directs motor responses; in higher vertebrates it is also the centre of learning. In humans and some primates, differences exist, primarily in the division of the globus pallidus into external and internal regions, and in the division of the striatum. It is the caudal part of the forebrain (prosencephalon) that occupies the central region of the brain.; substantia nigra: Brain structure located in the midbrain that plays an important role in reward and movement. And yet another way of organizing is to recognize a structure called the brain stem, consisting of the midbrain, the pons, and the medulla — that is, the midbrain and the hindbrain except for the cerebellum. It is composed of 3 sections in descending order: the midbrain, pons, and medulla oblongata.4 kg (3 pounds) and is made up of billions of cells called neurons.

Five secondary vesicles form, including the telencephalon and diencephalon from the forebrain; the mesencephalon is retained; and the metencephalon and the myelencephalon from the hindbrain. The reticular formation consists of more than 100 small neural networks with varied functions including motor control, cardiovascular control, pain modulation
Neural pathways anatomy The central nervous system (CNS) contains numerous nerve fibers that group together to form pathways between its various parts. It is situated along the anterolateral aspect of the periaqueductal grey matter and lies ventral to the inferior colliculi at the level of the midbrain. It acts as a conduit between the forebrain above and the pons and cerebellum below. 16.The brain is the largest cluster of neurons in the body and is typically located in the head, usually near organs for special senses such as vision, hearing and olfaction. The frontal lobe is located behind the forehead, and is responsible for considerable of the complex cognitive function: Reasoning, imagination, planning, values and behavior. Initially, the anterior end of the tube forms a crook, giving it the shape of a cane handle (Figure 22. Otak dibagi menjadi belahan kiri dan kanan oleh pita serat yang disebut corpus callosum .
