INTRODUCTION Septo-optic dysplasia (De Morsier syndrome) is defined as the association between optic nerve hypoplasia, midline central nervous system malformations and pituitary dysfunction. CASE REPORT Third child born to nonconsanguineous parents, female, adequate pre-natal medical care, cesarean term delivery due to breech presentation, Apgar score 3 at the first minute and 8 at 5 minutes,...
the cholinergic and gabaergic .bers of the medial septal/diagonal band of broca (ms/db) area project to the hippocampus and constitute the septo-hippocampal pathway, which has been proven to play a role in learning and memory. in addition, the hippocampus has bidirectional connections with the septum so that to self-regulate of cholinergic input. the activity of septal and hippocampal neurons i...
We investigated the role of the septo-hippocampal cholinergic projection in anxiety, spatial novelty preference, and differential reward for low rates of responding (DRL) performance. Cholinergic neurons of the rat medial septum (MS) and the vertical limb of the diagonal band of Broca (VDB) were lesioned using the selective immunotoxin, 192 IgG-saporin. Rats were then tested on several behavior...
Before the onset of locomotion, the hippocampus undergoes a transition into an activity-state specialized for the processing of spatially related input. This brain-state transition is associated with increased firing rates of CA1 pyramidal neurons and the occurrence of theta oscillations, which both correlate with locomotion velocity. However, the neural circuit by which locomotor activity is l...
