Physiological studies suggest spatial representation gradients along the CA1 proximodistal axis. To determine the underlying anatomical basis, we quantitatively mapped canonical and noncanonical inputs to excitatory neurons in dorsal hippocampal CA1 along the proximal-distal axis in mice of both sexes using monosynaptic rabies tracing. Our quantitative analyses show comparable strength of subic...

Background: The study determined the histological layers of cerebral cortex and hippocampus albino rat brain samples has been used in study. Cerebral is composed Molecular layer, external granular, pyramidal internal granular layer interior layer. are alveus, stratum oriens, pyramidale, radiatum, lacunosum moleculare. aim to analyze detailed features rats at magnification 10X,100X,40X. By using...

AIMS In the present study, the effects of bilateral intra-dorsal hippocampal (intra-CA1) injections of cholinergic agents on muscimol state-dependent memory were examined in mice. MAIN METHODS A single-trial step-down passive avoidance task was used for the assessment of memory retention in adult male NMRI mice. KEY FINDINGS Pre-training intra-CA1 administration of a GABA-A receptor agonist...

In the present study, the effects of intra-dorsal hippocampal (intra-CA1) injections of nitric oxide (NO) agents on muscimol state-dependent memory were examined in mice. A single-trial step-down passive avoidance task was used for the assessment of memory retrieval in adult male NMRI mice. Post-training intra-CA1 administration of a GABAA receptor agonist, muscimol (0.05 and 0.1 μg/mouse) dose...

In the present study, effects of intra-hippocampal CA1 (intra-CA1) injections of GABA(B) receptor agonist and antagonist on the acquisition and expression of morphine-induced place preference in male Wistar rats have been investigated. Subcutaneous administration of different doses of morphine sulphate (0.5-6 mg/kg) produced a dose-dependent conditioned place preference (CPP). Using a 3-day sch...

CA1 cells receive direct input from space-responsive cells in medial entorhinal cortex (MEC), such as grid cells, as well as more nonspatial cells in lateral entorhinal cortex (LEC). Because MEC projects preferentially to the proximal part of the CA1, bordering CA2, whereas LEC innervates only the distal part, bordering subiculum, we asked if spatial tuning is graded along the transverse axis o...

Using first-principle spin-density functional computations, the structural, magnetic, and electronic properties of Cr- V-doped diluted magnetic semiconductors Ca1-xCrxS Ca1-xVxSe at x = 0.25 in B1 (NaCl) phase are explored. Elastic constants structural (lattice constants, bulk modulus, its pressure derivative) were calculated used to establish structure stability. Plots TDOS PDOS transition met...
