Abstract: The fact that there is a complex and bidirectional communication between the immune nervous systems has been well demonstrated. Lipopolysaccharide (LPS), component of gram‐negative bacteria, widely used to systematically stimulate system generate profound physiological behavioural changes, also known as ‘sickness behaviour’ (e.g. anhedonia, lethargy, loss appetite, anxiety, sleepiness). Different ethological tools have analyse modifications induced by LPS; however, many researchers...
Neural circuits in the dorsal periaqueductal grey matter (DPAG) play an important role integration of defensive behaviour. As considerable numbers μ and κ opioid receptors have been found this region, we studied effects morphine, [ 3 H]-[H- d -Phe-Cys-Tyr- -Trp-Orn-Thr-Pen-Thr-NH 2 ] (CTOP), a selective peptide antagonist for receptors, U-50488H, specific agonist nor-binaltorphimine (nor-BNI), long-lasting injected into DPAG rats submitted to corral method, conditioned place preference test....
The amygdala and ventral portion of the periaqueductal gray (vPAG) are crucial for expression contextual freezing behavior. However, it is still unclear whether also plays a role in defensive behaviors induced by electrical stimulation dorsal (dPAG). In present study, rats were implanted with electrodes into dPAG determination thresholds escape responses before after sham or electrolytic lesions amygdala. Animals then submitted to context fear conditioning procedure. Amygdala disrupted but...
Isolation causes important changes in the behavioral reactivity of rats to environmental stimuli. These include deficit sensorimotor gating and altered fear-like responses aversive Measures ultrasound vocalizations at 20–22 kHz when are exposed threatening conditions, such as novelty, have been taken a good measure fear. The fear-potentiated startle loud sounds prepulse inhibition tests considered reliable indicators anxiety attention impairments, respectively. Rats reared under conditions...
Abstract Exposure to stress and prolonged exposure alcohol leads neuronal damages in several brain regions, being the medial prefrontal cortex (mPFC) one of most affected. These changes presumably reduce ability organism cope with these stimuli may underlie a series maladaptive behaviours among which include drug addiction withdrawal. Drug‐addicted individuals show pattern behavior similar patients lesions mPFC. This impairment decision‐making could be mechanisms responsible for transition...
