The discovery of neuropeptides in mammalian nervous tissue has proceeded at an astonishing pace in recent years, encouraged by novel detection techniques which allow peptides to be extracted and sequenced before their biological activity has been determined (Mutt 1983; Sudcliffe et al. 1983). Most of these methods, poached from molecular biology, are nowadays reversing former trends which evolved either as a systematic search for factors known to control pituitary hormone release (vasopressin and oxytocin), for instance, or as an endeavour to find endogenous ligands for newly discovered receptors (the endorphins) (see Krieger 1983 for review). Neuropeptide tyrosine (NPY) has emerged as an important member of this new generation of peptides, not least because it is the most abundant and widely distributed in the mammalian brain. However, despite the considerable attention this peptide has attracted, we are far from understanding its functional significance. The following account traces the history of NPY and appraises some of the literature in an attempt to raise some speculation concerning its function; several reviews on this peptide already exist (Emson and de Quidt 1984; Solomon 1985; Allen and Bloom 1986; Gray and Morley 1986), Particular attention is paid to studies which have recently suggested that NPY might be involved with the pathogenesis of two neurodegenerative disorders, Huntington's chorea and Alzheimer's disease.

Neurosci. 11 (1991) 2321-2331 [16].] were investigated in mice injected with methamphetamine (2 mg/kg, s.c., one to five times). The ambulatory activity enhanced by either acute or chronic methamphetamine injection was delayed or diminished by lithium chloride (LiCl) pretreatment [R.G. Fessler, R.D. Sturgeon, S.F. London, H.Y. Meltzer, Effects of lithium on behaviour induced by phencyclidine and amphetamine in rats. Psychopharmacology 78 (1982) 373-376 [3].]. How the Li-sensitive c-Fos expression in the dorsolateral geniculate nucleus and striatum is related to methamphetamine-induced behavioral excitation is unclear. This protocol, in combination with c-Fos expression of mouse cerebral regions, may provide a useful tool for quantitation of ambulatory activity during c-Fos expression.
