Numerous studies show that people who exercise regularly have a prefrontal cortex and
medial temporal cortex that are larger in volume versus people do not exercise.
We consider recent experiments correlating neuronal activity
the medial temporal cortex (area MT) to performance during two - alternative discrimination tasks [4, 5], and show how the different tasks used in these studies either isolate the effects of «high - slope» encoding [5] or «peak - firing - rate» encoding [4].
The orbital prefrontal cortex negatively interacted with the left
medial temporal cortex only at the acupuncture points.
Conscious recollection depends on the hippocampus and prefrontal cortex, whereas familiarity depends on regions of
the medial temporal cortex.

As Dr. Robert Cantu explains in his 2012 book, Concussions and Our Kids, [15] it «takes more than one type of test to compile a comprehensive baseline,» because neurocognitive tests measure the thinking and reasoning parts of the brain (
medial temporal lobe and front lobe), but concussions «also may cause trauma to the calcarine
cortex, which is in the back of the brain and controls vision, and the cerebellum, at the top of the neck, where balance and coordination are measured.
«Our results suggest that aerobic exercise may have a positive effect on the
medial temporal lobe memory system (which includes the entorhinal
cortex) in healthy young adults.
The
medial temporal structures, including the hippocampus and the entorhinal
cortex, are critical for the ability to transform daily experience into lasting memories.
Decades of research and clinical observations have established that declarative memory, the ability to remember recently experienced facts and events, depends on the hippocampus and associated structures in the
medial temporal lobe, including the entorhinal, perirhinal, and parahippocampal
cortexes.1
The first of these two research programs involves the independent mnemonic contributions of the different
medial temporal lobes structures, the extent to which different
medial temporal lobe structures must interact in storing information and their interaction with the prefrontal
cortex.
These 2 modalities were used to investigate connectivity within the default mode network, a set of brain regions — including
medial prefrontal
cortex (MPFC),
medial temporal lobes (MTLs), and posterior cingulate
cortex (PCC) / retropslenial
cortex (RSC)-- implicated in episodic memory processing.
The default - mode network (DMN) is a prominent network which includes the posterior cingulate
cortex (PCC),
medial prefrontal
cortex (mPFC),
medial temporal lobes (MTL), and angular gyrus (AG).
Specifically, FC decreases were identified in regions implicated in episodic memory (EM) processing (posteromedial
cortex, ventral
medial prefrontal
cortex, and angular gyrus), whereas connectivity increases were detected in dorsal and anterior
medial prefrontal and lateral
temporal cortices.
Cluster a (a) shows the default mode network, consisting of frontal regions, including superior frontal gyrus (BA 8/9) and
medial frontal gyrus (BA 10/11) and precuneus / posterior cingulate
cortex (BA 23/31) and bilateral regions overlapping middle / superior
temporal tyrus (BA 21/39) and inferior / superior parietal
cortex (BA 39/40).
Ins, insula; SS, somatosensory operculum; dTP, dorsal

In this model, the cognitive control system including prefrontal and parietal regions and the anterior cingulate is crucial to decision - making but is functionally dominated by a second affective system that includes regions which are important to processing reward and social and emotional salience, including but not limited to the amygdala, ventral striatum, orbitofrontal
cortex,
medial prefrontal
cortex, and the superior
temporal sulcus.
