	Frontal lobe - Wikipedia, the free encyclopedia
		The frontal lobe is an area in the brain of vertebrates.
		Located at the front of each cerebral hemisphere, frontal lobes are positioned in front of (anterior to) the parietal lobes.
		People that have damaged frontal lobes may experience problems with these aspects of cognitive function, being at times impulsive; impaired in their ability to plan and execute complex sequences of actions; perhaps persisting with one course of action or pattern of behavior when a change would be appropriate (perseveration).

		The boundaries of the parietal lobe are not precise, except for its rostral border – the central sulcus.
		The frontal lobe is the largest of the brain lobes and is comprised of four gyri, precentral gyrus that parallels the central sulcus, and three horizontal gyri: the superior, middle, and inferior frontal gyri.
		Caudal to the postcentral gyrus is the inferior parietal gyrus.

		Sitting at the junction of the temporal, parietal, and occipital lobes, the inferior region (which includes the angular and supramarginal gyri) has no strict anatomical boundaries, is partly coextensive with the posterior-superior temporal gyrus, and includes part of area 7 as well as area 37.
		Inferior parietal neurons are involved in the assimilation and creation of cross modal associations and act to increase the capacity for the organization, labeling and multiple categorization of sensory-motor and conceptual events (Geschwind, 1965; Joseph 1982).
		With right parietal involvement patients tend to have trouble with the general shape and overall organization, the correct alignment and closure of details, and there may be a variable tendency to ignore the left half of the figure or to not fully attend to all details.

	JYI: A Review of Parietal Lobe Functioning in Planning and Updating Motor Movements
		Not surprisingly, the parietal cortex (including the parietal operculum, or secondary somatosensory cortex, and the left inferior parietal cortex) was more active in the deluded passive movement than in the active movement condition.
		If the parietal areas are multisensory, then a change in position of the limb (which provides proprioceptive impulses) should be as effective as visual sensations in restoring knowledge of the location of the limb.
		Activity in the parietal cortex may be correlated with the comparison mechanism of the forward model or the conscious sensation of intention may be correlated with this change in the perceived timing of action and effect of the intentional binding explanation.

	Brain - Summary
		The frontal lobe is the largest of all the lobes and is composed of the area anterior to a deep sulcus (the 'dips' on the brain surface) called the central sulcus that runs horizontally across the brain.
		The parietal lobe extends posteriorly from the central sulcus to the parieto-occipital sulcus.

		Parietal lobe seizures masquerading as panic attacks have been reported (Alemayehu et al 1995), but this ictal manifestation may be more often associated with right temporal lobe seizure origin (Sazgar et al 2003).

		The parietal lobe is traced in the sagittal plane.
		The parietal lobe is defined as the portion of the cerebrum superior and anterior to the parieto-occipital sulcus, posterior to the central sulcus, and superior to the corpus callosum (Figure 1).
		As you move laterally, the corpus callosum disappears and the parietal lobe is then traced as all matter above the lateral ventricle down to the tip of the hippocampus (Figure 3).

	E-epilepsy - Occipital and parietal lobe epilepsies (Site not responding. Last check: )
		Epileptic seizures of parietal and occipital origin are heterogeneous and mainly characterised by the presenting auras, although the most dramatic clinical manifestations may reflect spread, and overshadow the focal origin.
		Spread seems to be to the parietal and frontal regions when the discharge originates in the supracalcarine region, but to the ipsilateral temporal lobe when the epileptic activity arises in the infracalcarine cortex.
		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.

		Parietal Lobe Damage: Damage to the front part of the parietal lobe on one side causes numbness and impairs sensation on the opposite side of the body.

	Parietal Lobe Function
		Damage to the left parietal lobe can result in what is called "Gerstmann's Syndrome." It includes right-left confusion, difficulty with writing (agraphia) and difficulty with mathematics (acalculia).
		Damage to the right parietal lobe can result in neglecting part of the body or space (contralateral neglect), which can impair many self-care skills such as dressing and washing.
		This is characterized by the inability to voluntarily control the gaze (ocular apraxia), inability to integrate components of a visual scene (simultanagnosia), and the inability to accurately reach for an object with visual guidance (optic ataxia) (Westmoreland et al., 1994).

	Neurological Exam: Cerebrum: Lesions: Abscess - Parietal Lobe
		There is a upper motor neuron syndrome involving the left face, arm, and leg caused by injury, at cortical levels, of cells of origin of the right corticospinal and related fiber tracts; fibers of this tract originate from both the frontal and parietal lobes.
		Such sensory deficits, i.e., acquisition and recognizing primary sensory data but with deficits in integrative functions as demonstrated by graphesthesia, extinction, tactile agnosia, etc., occurs with lesions of the parietal lobe, especially in the area of the supramarginal and angular gyri (areas 40 and 39).
		Failure to pay attention to the left space as indicated by his drawings, impaired visual recognition, inattention to people, and dressing apraxia is common with lesions of the right parietal lobe.

		The parietal lobes are located above the temporal lobe and between the central sulcus, a deep crease in the neocortex, and the occipital lobe of the brain.
		However, the many different responsibilities of the parietal lobe are delegated to the right and left sides, as they are each responsible for different functions.
		A neurologist would refer a patient with a damaged right parietal lobe to a neurosurgeon for treatment; however, because these disorders originate from damage to the brain, the work of a neurosurgeon would not eliminate the problem; but rather attempt to improve the patient's quality of life.
