		Messages can travel from one bulge on the brain to another (gyri to gyri), from one lobe to another, from one side of the brain to the other, from one lobe of the brain to structures that are found deep in the brain, e.g.
		Occipital Lobes — These lobes are located at the back of the brain and enable humans to receive and process visual information.
		The occipital lobe on the right interprets visual signals from the left visual space, while the left occipital lobe performs the same function for the right visual space.

		The occipital lobe has a considerable variability with respect to the sulcal and gyral pattern on its convex surface.
		The most frequently observed sulci include the "transverse occipital sulcus," the "lateral occipital sulcus," and the "lunate sulcus." The convolutions are also quite variable, but usually divide much of the occipital lobe into the "superior" and "inferior lateral occipital gyri".
		The "parieto-occipital sulcus" which helps to form the border between the parietal and occipital lobes is the "parieto-occipital arcus." The middle surface of the occipital lobe is marked by the "calcarine" and the "parieto-occipital sulci," which form the boundaries of the wedge-shaped lobule called the "cuneus."

	ScienceDaily: Occipital lobe
		The occipital lobe is the visual processing center of the mammalian brain.
		The primary visual cortex is Brodmann area 17, located in the interior portion of the occipital lobe at the calcarine sulcus and sometimes continuing onto the surface of the lobe.

		The occipital lobes are the smallest of the cortical divisions and lie at the most caudal aspect of the cerebrum.
		Lesions of the occipital lobes are manifested as changes in visual perception, and a congruent homonymous visual field cut is frequently present.
		In cortical blindness, or blindness caused by bilateral destruction of the occipital lobes or their afferents, retention of pupillary responses reflects intact visual input to the brain stem.

		Human V1 is located on the medial side of the occipital lobe within the calcarine sulcus; the full extent of V1 often continues onto the posterior pole of the occipital lobe.
		The lobes rest on the tentorium cerebelli, a process of dura mater that separates the cerebrum from the cerebellum.
		Cells on the posterior aspect of the occipital lobes' gray matter are arranged as a spatial map of the retinal field.

	E-epilepsy - Occipital and parietal lobe epilepsies
		Seizures from the occipital lobes and the parieto-occipital junction are characterised by visual phenomena, but visual auras may occur in epilepsy affecting any part of the visual pathways.
		Occipital foci are often widespread and wandering between the occipital pole and the anterior temporal lobes.
		Electrical abnormalities may be confined to the temporal lobes, and depth electrode studies in patients with complex partial seizures have in some cases revealed an occipital origin of the epilepsy, although such origin has not been reflected in the clinical picture of the seizures or revealed by scalp EEG.

		The occipital lobe is in the rear portion of the brain buttressed up against the back of the skull.
		Running down the center of the occipital lobe is the Y-shaped calcarine fissure.
		While the occipital lobe's most important function is converting neural impulses into images, the occipital lobe is only a pit stop on the way to sight.

	Idiopathic photosensitive occipital lobe epilepsy
		This may indicate that an age-related hyperexcitability to photic stimuli could become apparent at around puberty in the occipital lobe; this is similar to the hyperexcitability to somesthetic stimuli observable during childhood in the somatosensory cortex of children with benign rolandic epilepsy.
		The diagnosis of idiopathic photosensitive occipital lobe epilepsy is based on the association of occipital seizures that appear on exposure to environmental visual stimuli with a photoparoxysmal EEG response, usually predominating over the occipital regions, in adolescents who have no other neurologic abnormalities.
		A shifting of the occipital ictal discharge from side to side and a critical role of the Oz electrode in demonstrating the ictal discharge associated with the elementary initial visual symptoms is also typical (Guerrini et al 1995).

	SparkNotes: Brain Anatomy: Parietal and Occipital Lobes
		The major function of the parietal lobe is to mediate attention, but it is also involved in long-term memory and somatic sensory perception.
		The association cortex of the parietal lobe, together with a section of the temporal lobe, is responsible for long-term storage of vocabulary words.
		The occipital lobe comprises the most posterior section of the brain, situated posterior to the parieto-occipital sulcus and directly above the cerebellum (see figure).

		As noted, whereas the temporal lobes perform complex form recognition and central and upper visual field analysis, the parietal lobes observe the periphery and lower visual field (where the hands and feet are most likely to be viewed) and together these cortical regions compute and make possible, eye-hand, or hand-object coordination.
		That is, tissues in the midbrain, thalamus, or the temporal/parietal lobe, continue to process visual input, but are nevertheless, disconnected from the "dominant" stream of verbal consciousness mediated by the left hemisphere due to the injury to the occipital lobe.
		The occipital lobes also appear to be lateralized in regard to certain capabilities such as facial recognition.

		If the middle part of the frontal lobe is damaged, the ability to move the eyes, to perform complex movements in the correct sequence, or to say words may be impaired.
		If the front part of the frontal lobe is damaged, the result may be impaired concentration and reduced fluency of speech; apathy, inattentiveness, and delayed responses to questions; or a striking lack of inhibition, including socially inappropriate behavior.
		When the occipital lobe on both sides of the brain is damaged, cortical blindness results.

	What are the Different Kinds of Epilepsy
		Occipital lobe epilepsy is like frontal and temporal lobe epilepsies, except that the seizures usually begin with visual hallucinations, rapid blinking, and other symptoms related to the eyes.
		Parietal lobe epilepsy is similar to other types in part because parietal lobe seizures tend to spread to other areas of the brain.
		About 80% of these complex partial seizures take place in the temporal lobe of the brain, which is close to the ear, and they are sometimes called temporal lobe seizures.

		The Occipital Lobe is almost entirely used for initial visual reception, which it then passes to the temporal and parietal lobes.
		The parietal lobe is a somatosensory cortex, and a secondary visual processor.
		While the temporal lobe is responsible for what an object is, the parietal lobe is instead responsible for determining where an object is located.

	Occipital Lobe
		The Peristriate region of the occipital lobe is involved in visuospatial processing, discrimination of movement and color discrimination (Westmoreland et al., 1994).
		Damage to one side of the occipital lobe causes homonymous loss of vision with exactly the same "field cut" in both eyes.
		The occipital lobe is the main target for axons from the thalamic nuclei that receive input from the visual pathways.

		Definition of the anterolateral occipital lobe limit in anatomical specimens and with neuroimaging
		ABSTRACT - The anterolateral limit of the occipital lobe was studied in anatomical specimens and with neuroimaging.
		In the imaging studies, especially magnetic resonance, it was possible to identify the preoccipital notch and/or a protuberance in the cranial vault related to this notch, besides the parieto-occipital sulcus and lambdoid suture, making possible, therefore, the definition of the anterolateral limit of the occipital lobe.

	Your baby's brain: the occipital lobe
		The occipital lobe (located near the back of the head) controls vision and visual recognition (the ability to understand what you're seeing).
		The neural pathways that relay visual information to the brain are also not yet mature, so it is difficult for a newborn to understand what he's seeing.
		In order to develop these pathways and the vision controls located in the occipital lobe, your baby needs to see a variety of objects.

		These fibers form a a chiasma, a crossing which then transmits the information to the thalamus' lateral geniculate bodies, where the perception of depth occurs, and then moves on to the occipital lobes' primary visual cortex.
		However, as much as we presently know about the process of seeing, there remains the mystery as to "why electrical signals arriving in the visual cortex should be experienced as vision, while exactly the same kind of electrical signals, arriving in another part of the brain"are experienced as respective senses.
