introduction: the role of different parts of the extended amygdala in metabolic signs of stress is not well understood. in the present study, we decided to evaluate the impact of the shell part of nucleus accumbens (nac) on metabolic disturbance induced by electro foot shock stress using transient inactivation method in the rat.  methods: male wistar rats (w: 230-250 g) were canuulated unilater...

objective(s):previous studies demonstrated a functional similarity between vertebrate and honey bee nervous systems. the aim of the present study was to compare the effects of heroin and iranian street kerack, a combination of heroin and caffeine, on sensory threshold and locomotor activity in honey bees. materials and methods: all drugs were given orally to honey bees 30 min before each experi...

diabetes mellitus is one of the most common causes of neuropathy. although antioxidant and antidiabetic effects of the aqueous extract of purslane (portulaca oleracea) (aeop) have been demonstrated before by other researchers, we did not find any study that assessed the psychobiological effects of aeop in diabetes induced animals. thirty ovariectomized (ovx) female wistar rats were randomly div...

parkinson's disease is a degenerative disorder of the central nervous system. the motor symptoms of parkinson's disease result from the death of dopamine-generating cells in the substantia nigra, a region of the midbrain the cause of this cell death is unknown. homocysteine (hcy) is a non-protein amino acid. it is a homologue of the amino acid cysteine. the elevated levels of homocysteine in pl...

introduction: in this study, we investigated the role of n-methyl-d-aspartate (nmda) receptors in the ventral hippocampus (vh) and their possible interactions with gabaa system on anxiety-like behaviors. methods: we used an elevated-plus maze test (epm) to assess anxiety-like behaviors and locomotor activity in male wistar rats. results: the results showed that intra-vh infusions of different d...

This study examined the relationship between motor skill competence, and physical activity in 8–9 years-old girls (N=352). Locomotor and object control skill competence was assessed, using the Test of Gross Motor Development-2, and the Physical Activity Questionnaire for Children was used to assess physical activity. Regression analysis revealed that locomotor proficiency accounted for 20% (P...
