temporal lobe

The lower lateral lobe of either cerebral hemisphere, located in front of the occipital lobe and containing the sensory center of hearing in the brain.

temporal lobe

(Anatomy) the laterally protruding portion of each cerebral hemisphere, situated below the parietal lobe and associated with sound perception and interpretation: it is thought to be the centre for memory recall

The investigator analyzed four brain regions of interest: the medial temporal lobe and adjacent hippocampal white matter and the posterior cingulate and adjacent white matter in the splenium.
Medial temporal lobe atrophy is associated with MCI subtypes and measures of cognition but not vascular risk factors, Laura van de Pol reported during the DESCRIPA session.
The NYU researchers-Yuji Naya, an associate research scientist, and Professor Wendy Suzuki, both of NYU's Center for Neural Science-focused their study on the brain's medial temporal lobe (MTL) - known for its significant role in declarative memory-that is, memory of facts and events or episodes.
Patients in the eating disorder groups showed less activity in the ventral occipitotemporal cortices in response to body stimuli than the healthy controls, and the aversion ratings of body stimuli correlated positively with activity in several brain regions, including the medial and apical prefrontal cortices and the inferior medial temporal lobe.
The patients could not remember the locations of four or more objects because doing so involved tapping into long-term memory functions in the medial temporal lobe.
Although a whole network of brain areas support memory, the researchers focused their study on the medial temporal lobe, an area deep within the brain believed to be most heavily involved in episodic memory.
Previous studies discovered the medial temporal lobe to be the most vulnerable brain region in the early stages of Alzheimer's accumulating damaged tau proteins in the form of neurofibrillary tangles.
Amateurs have been found to rely more heavily on the medial temporal lobe and hippocampus regions, which are responsible for short-term memory and processing new information (Nature 412[6847]:603, 2001).
The neuroimaging results showed significant activity in two regions of the brain during the encoding of impression-relevant information-the first, the amygdala, is a small structure in the medial temporal lobe that previously has been linked to emotional learning about inanimate objects, as well as social evaluations based on trust or race group.
During the study, the research team used a new visual rating system to evaluate the severity of shrinkage, or atrophy, in the brain's medial temporal lobe - specifically in three structures essential for the conscious memory of facts and events.
Remembering things over longer spans of time involves the brain's hippocampus, housed deep inside the medial temporal lobe.
This phenomenon may also be associated with major depression, seizures, medications (such as topiramate), and right medial temporal lobe vascular lesions.
