The way hippocampal neurons function during stress in old age (critical times of life) is dependent on brain derived neurotrophin factor (BDNF). This study examined the influence of acute and chronic forced swim (FS) or high‑light open field (HL‑OF) stimulation on the density of BDNF immunoreactive (ir) neurons in the hippocampal pyramidal layers of CA1, CA2, CA3 regions and the granular layer of...
Proinflammatory cytokine - interleukin ip (IL-ip) plays an important role in stress reactions in the structures of limbic system. The impact of stress on IL-ip may depend on the ontogenetic age. The study examined the influence of acute and chronic exposure to forced swim (FS) or high-light open-field (HL-OF) stressors on neurons containing IL-ip. Double immunofluorescence staining was used to reveal...
The influence of compounds interacting with cholinergic systems on field potentials evoked in layer II/III horizontal connections was investigated in rat motor cortex in vitro. The cholinesterase inchibitor eserine (10 mM) decreased field responses by 20?2%. This inhibito effect could be prevented by preincubation with atropine (10 mM) Application of 5 mM carbachol resulted in reduction of the responses...
