However, other studies have found relatively weak responses of the hippocampal formation
on memory tests similar to Schacter's high recall, explicit condition, according to Steven E.
The size of the hippocampal formation
in the amnesia patients was just under half that of the healthy controls, the investigators report in the Sept.
Our study reporting number of neurons in dog hippocampal formation
is probably the first.
Dysfunction indicated by abnormal cerebral blood volume in the CA1 subfield of the hippocampal formation
is associated with schizophrenia and related psychotic disorders to the extent that it predicts disease progression in prodromal patients and correlates with clinical symptoms in both prodromal and schizophrenia patients, a small study has found.
Researchers review recent findings, particularly in psychology and pharmacology, on such aspects as molecular mechanisms of learning and memory as revealed by research on Ca2+/calmodulin-dependent protein kinase II, motor learning in the cerebellum, seizure-induced synaptic plasticity, cocaine addiction, the medial pre-frontal cortex, mnemonic encoding by hippocampal formation
place cells, and dopamine-dependent synaptic plasticity in the cortico-basal ganglia-thalamocortical loops as mechanisms of visual attention.
The hippocampal formation
was stained using the Rapid Golgi protocol (Valverde 1993), and the cerebellum was stained using a modified Golgi-Cox staining protocol (Morest 1981) in tissue sections (100 [micro]m), prepared using a sliding microtome (American Optical, New Haven, CT).
