An identifiable segment of an antenna radiation pattern. (Note: A lobe is characterized by a localized maximum bounded by identifiable nulls.)
A pair of channels between a data station and a lobe attaching unit, one channel for sending and one for receiving, as seen from the point of view of the attached data station.
The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior.
The frontal lobes are extremely vulnerable to injury due to their location at the front of the cranium, proximity to the sphenoid wing and their large size.
The left frontal lobe is involved in controlling language related movement, whereas the right frontal lobe plays a role in non-verbal abilities.
Their increasing significance and clinical relevance is noted by the recent publication of several monographs on frontal lobe syndromes (5,6) and the growing literature on various frontal lobe disorders, for example, frontal lobe dementias and frontal lobe epilepsies.
The frontal lobes are anatomically represented by those areas of the cortex anterior to the central sulcus, including the main cortical areas fur the control of motor behavior.
The paradigm of frontal lobe dementia is that described by Pick in 1892, which was associated with circumscribed atrophy of both the frontal and temporal lobes.
