TRPV1 receptor mediates glutamatergic synaptic input to dorsolateral periaqueductal gray (dl-PAG) neurons.
The purpose of this study was to determine the role of transient receptor potential vanilloid type 1 (TRPV1) receptor in modulating neuronal activity of the dorsolateral periaqueductal gray (dl-PAG) through excitatory and inhibitory synaptic inputs. First, whole cell voltage-clamp recording was performed to obtain the spontaneous miniature excitatory postsynaptic currents (mEPSCs) and inhibitor...
متن کاملMuscarinic modulation of synaptic transmission via endocannabinoid signalling in the rat midbrain periaqueductal gray.
The midbrain periaqueductal gray (PAG) is involved in organizing behavioral responses to threat, stress, and pain. These PAG functions are modulated by cholinergic agents. In the present study, we examined the cholinergic modulation of synaptic transmission in the PAG using whole-cell voltage-clamp recordings from rat midbrain slices. We found that the cholinergic agonist carbachol reduced the ...
متن کاملActions of cannabinoids on membrane properties and synaptic transmission in rat periaqueductal gray neurons in vitro.
The midbrain periaqueductal gray (PAG) is a major site of cannabinoid-mediated analgesia in the central nervous system. In the present study, we examined the actions of cannabinoids on rat PAG neurons in vitro. In brain slices, superfusion of the cannabinoid receptor agonist WIN55,212-2 inhibited electrically evoked inhibitory and excitatory postsynaptic currents in all PAG neurons. The endogen...
متن کاملEffect of the {mu} opioid on excitatory and inhibitory synaptic inputs to periaqueductal gray-projecting neurons in the amygdala.
Opioids are potent analgesics, but the sites of their action and cellular mechanisms are not fully understood. The central nucleus of the amygdala (CeA) is important for opioid analgesia through the projection to the periaquaductal gray (PAG). In this study, we examined the effects of mu opioid receptor stimulation on inhibitory and excitatory synaptic inputs to PAG-projecting CeA neurons retro...
