From April 2009 to December 2011, 44 dead hedgehogs (Erinaceus europaeus) were collected incidentally from areas of Urmia, Iran. The overall prevalence of helminth infections was 95.0%. Specific parasites and their prevalences were: Physalopteraclausa(93.0%), Crenosoma striatum (61.0%), Capillariaaerophila(9.0%), Capillariasspp.(4.0...

Background & Aims: There is no agreement on the protective effect of exercise on neurodegeneration processes, and the mechanisms responsible for exercise benefits in Parkinson disease (PD) yet. In this study we investigated the protective effect of 4 weeks of treadmill running with low intensity on the IGF-1, dopamine and tyrosine hydroxylase levels in the striatum of parkinsonian rats ind...

Introduction: Morphine is a potent analgesic but its continual use results in analgesic tolerance. Mechanisms of this tolerance remain to be clarified. However, changes in the functions of μ-opioid and N-Methyl-D-aspartate (NMDA) receptors have been proposed in morphine tolerance. We examined changes in gene expression of the NMDA receptor subunit 1 (NR1) at mRNA levels i...

The striatum consists of GABAergic projection neurons and various types of interneurons. Despite their relative scarcity, these interneurons play a key role in information processing in the striatum. One such class of interneurons is the cholinergic tonically active neurons (TANs). In the dorsal striatum, TANs are traditionally considered to be responsive to events of motivational significance....

Neurons in the ventral striatum (VS) fire to cues that predict differently valued rewards. It is unclear whether this activity represents the value associated with the expected reward or the level of motivation induced by reward anticipation. To distinguish between the two, we trained rats on a task in which we varied value independently from motivation by manipulating the size of the reward ex...

Rats trained in a dual-solution cross-maze task, which can be solved by place and response strategies, predominantly used a response strategy after extensive training. This paper examines the involvement of the medial and lateral dorsal striatum (mDS and lDS) in the choice of these strategies after partial and extensive training. Our results show that rats with lDS and mDS lesions used mainly a...
