The pedunculopontine tegmental nucleus (PPTg) contains a population of cholinergic
neurons (the Ch5 group) and non-cholinergic neurons. There appears to be functional …

This is a review of our current knowledge about the role of the periaqueductal grey (PAG) in
vocal control. It shows that electrical stimulation of the PAG can evoke species-specific calls …

The amplitude of the acoustic startle response (ASR) is markedly reduced when the startle
eliciting pulse is preceded by a weak, non-startling stimulus at an appropriate lead time …

Appetitive behaviors of rats were monitored in a runway situation following central infusions
of neuroactive substances into brain areas implicated in electrical self-stimulation …

Postsynaptic responses of dopamine (DA) neurons in the substantia nigra pars compacta
(SNc) to stimulation of the pedunculopontine tegmental nuclei (PPN) were studied in in vitro …

Data from the World Health Organization (National Institute on Aging,) and the National
Institutes of Health (He et al.,) predicts that while today the worldwide population over 65 …

Dopamine neurons in the midbrain respond to behavioral events and environmental stimuli.
Their different patterns of activation in turn modulate the activity of forebrain regions and …

Publisher Summary This chapter discusses the physiological and behavioral effects of
acetylcholin (ACh) in the cerebellum and cholinergic innervation of the cerebellum. The …

Antibodies directed against the C-terminus of the rat vesicular acetylcholine transporter mark
expression of this specifically cholinergic protein in perinuclear regions of the soma and on …

Reward seeking is controlled by conditioned stimuli (CSs). There is a positive relation
between mesocorticolimbic dopamine (DA) and the performance of learned reward-directed …
