The extrastriate cortex is the region of the occiptial cortex of the mammalian brain located next to the striate cortex (which is also known as the primary visual cortex). In terms of Brodmann areas, the extrastriate cortex comprises Brodmann area 18 and Brodmann area 19, while the striate cortex comprises Brodmann area 17. ...more on Wikipedia about "Extrastriate cortex"
The fourth ventricle is one of the four connected fluid-filled cavities within the human brain. These cavities, known collectively as the ventricular system, consist of the left and right lateral ventricles, the third ventricle, and the fourth ventricle. The fourth ventricle extends from the cerebral aqueduct (aqueduct of Sylvius) to the obex, and is filled with cerebrospinal fluid (CSF). ...more on Wikipedia about "Fourth ventricle"
In vertebrate anatomy, a ganglion is a tissue mass that contains the dendrites and cell bodies (or "somata") of nerve cells, in most case ones belonging to the peripheral nervous system. Within the central nervous system such a mass is often called a nucleus. An interconnected group of ganglia is called a plexus. ...more on Wikipedia about "Ganglion"
It is common to represent the complex 3-D organisation of the CNS through slices, which is called the stereotactic approach (stereo from solid object and tactic from tactus, touch). The most common orientation for slices are Axial, a horizontal slice, Coronal, a vertical slice that can show both ears, and Parasagital, a vertical slice that can show from the nose to the back of the head. A Sagital slice is the slice that divides the head in two equal left and right sides. A Parasagital slice is then any slice parallel to the Sagital slice. ...more on Wikipedia about "Glossary of anatomical terminology, definitions and abbreviations"
Grey matter is a category of nervous tissue with many nerve cell bodies and few myelinated axons. ...more on Wikipedia about "Grey matter"
The hippocampus is a part of the brain located inside the temporal lobe (humans have two hippocampi, one in each side of the brain). It forms a part of the limbic system and plays a part in memory and navigation. The name derives from its curved shape, which supposedly resembles that of a seahorse ( Greek: hippocampus). ...more on Wikipedia about "Hippocampus"
The human brain is the center of the central nervous system in humans as well as the primary control center for the peripheral nervous system. ...more on Wikipedia about "Human brain"

The median aperture of the brain (apertura medialis ventriculi quarte) or foramen of Magendie is an opening in the hollow nerve tube, connecting the fourth ventricle of the brain with the subarachnoid space. ...more on Wikipedia about "Median aperture"
The meninges (singular meninx) are the system of membranes that envelop the central nervous system. The meninges consist of three layers, the dura mater, the arachnoid mater, and the pia mater. ...more on Wikipedia about "Meninges"
The metencephalon is a developmental categorization of portions of the central nervous system. The metencephalon is composed of the pons and the cerebellum; contains a portion of the fourth ventricle; and the trigeminal nerve (CN V), abducens nerve (CN VI), facial nerve (CN VII), and a portion of the vestibulocochlear nerve (CN VIII). ...more on Wikipedia about "Metencephalon"
The myelencephalon is a developmental categorization of a portion of the central nervous system. The myelencephalon is composed of the medulla; contains a portion of the fourth ventricle; as well as the glossopharyngeal nerve (CN IX), vagus nerve (CN X), accessory nerve (CN XI), hypoglossal nerve (CN XII), and a portion of the vestibulocochlear nerve (CN VIII). ...more on Wikipedia about "Myelencephalon"
The neopallium ( Latin for "new mantle") is a part of the brain of mammals. It is the top layer of the cerebral hemispheres, about 2 mm thick, and is involved in higher functions such as sensory perception, generation of motor commands, spatial reasoning, and in humans, language and conscious thought. ...more on Wikipedia about "Neopallium"
Neurogenesis literally means "birth of neurons". Neurogenesis is most prevalent during pre-natal development and is the process by which neurons are created to populate the growing brain. ...more on Wikipedia about "Neurogenesis"
Neuropil is the feltwork of unmyelinated neuronal processes (axonal and dendritic) within the gray matter of the central nervous system. ...more on Wikipedia about "Neuropil"
The obex (from the Latin for barrier) is the point in the human brain at which the fourth ventricle narrows to become the central canal of the spinal cord. The obex occurs in the caudal medulla. ...more on Wikipedia about "Obex"
The olfactory nerve is the first of twelve cranial nerves. It consists of a collection of sensory nerve fibers that extend down from the olfactory bulb and pass through the many openings of the cribriform plate, a sieve-like structure. The specialized olfactory receptor neurons of the olfactory nerve are located in the olfactory mucosa of the upper parts of the nasal cavity. ...more on Wikipedia about "Olfactory nerve"
The pia mater (Latin: "tender mother", itself a translation from Arabic) is the delicate innermost layer of the meninges - the membranes surrounding the brain and spinal cord. ...more on Wikipedia about "Pia mater"
The posterior horn of the spinal cord is caudal (more towards the back/tail) to the anterior horn. It receives several types of sensory information from the body, including light touch, proprioception, and vibration. This information is sent from receptors of the skin, bones, and joints through sensory neurons that synapse in the dorsal root ganglion. ...more on Wikipedia about "Posterior horn"
In the anatomy of vertebrates, the prosencephalon (or forebrain) is the rostral-most portion of the brain. The prosencephalon, the mesencephalon (midbrain), and rhombencephalon (hindbrain) are the three primary portions of the brain during early development of the central nervous system. ...more on Wikipedia about "Prosencephalon"
The reticular activating system is the name given to part of the brain (the reticular formation and its connections) believed to be the centre of arousal and motivation in animals (including humans). It is situated at the core of the brain stem between the myelencephalon ( medulla oblongata) and metencephalon ( midbrain). ...more on Wikipedia about "Reticular activating system"
The Reticular formation is a part of the brain which is involved in stereotypical actions, such as walking, sleeping, and lying down. ...more on Wikipedia about "Reticular formation"
The rhombencephalon (or hindbrain) is a developmental categorization of portions of the central nervous system in vertebrates. ...more on Wikipedia about "Rhombencephalon"
The spinal cord is a part of the vertebrate nervous system that is enclosed in and protected by the vertebral column (it passes through the spinal canal). It consists of nerve cells. The cord conveys the 31 spinal nerve pairs of the peripheral nervous system, as well as central nervous system pathways that innervate skeletal muscles. ...more on Wikipedia about "Spinal cord"
