Noradrenergic modulation of wakefulness/arousal

CW Berridge, BE Schmeichel, RA Espaņa - Sleep medicine reviews, 2012 - Elsevier
The locus coeruleus-noradrenergic system supplies norepinephrine throughout the central
nervous system. State-dependent neuronal discharge activity of locus coeruleus …

Sleep neurobiology from a clinical perspective

RA Espaņa, TE Scammell - Sleep, 2011 - academic.oup.com
Many neurochemical systems interact to generate wakefulness and sleep. Wakefulness is
promoted by neurons in the pons, midbrain, and posterior hypothalamus that produce …

Hypocretin/orexin in arousal and stress

CW Berridge, RA Espaņa, NM Vittoz - Brain research, 2010 - Elsevier
… (alpha-helical CRF 12-41 ; Espaņa and Berridge, unpublished observations). This effect of
… < 0.01 significantly different from V + 0.7 (Espaņa and Berridge, unpublished observations). …

Afferents to the orexin neurons of the rat brain

K Yoshida, S McCormack, RA Espaņa… - Journal of …, 2006 - Wiley Online Library
Emotions, stress, hunger, and circadian rhythms all promote wakefulness and behavioral
arousal. Little is known about the pathways mediating these influences, but the orexin-…

Wake-promoting and sleep-suppressing actions of hypocretin (orexin): basal forebrain sites of action

RA Espana, BA Baldo, AE Kelley, CW Berridge - Neuroscience, 2001 - Elsevier
The hypocretins (orexins) are a newly identified peptide family comprised of two peptides,
hypocretin-1 and hypocretin-2. Recent observations suggest an involvement of these peptides …

Concomitant loss of dynorphin, NARP, and orexin in narcolepsy

A Crocker, RA Espaņa, M Papadopoulou, CB Saper… - Neurology, 2005 - AAN Enterprises
Background: Narcolepsy with cataplexy is associated with a loss of orexin/hypocretin. It is
speculated that an autoimmune process kills the orexin-producing neurons, but these cells …

Clozapine N-oxide administration produces behavioral effects in Long–Evans rats: implications for designing DREADD experiments

…, JK Shaw, SK Radhakrishnan, P Khare, RA Espaņa… - eneuro, 2016 - eneuro.org
Clozapine N-oxide (CNO) is a ligand for a powerful chemogenetic system that can selectively
inhibit or activate neurons; the so-called Designer Receptors Exclusively Activated by …

Demon voltammetry and analysis software: analysis of cocaine-induced alterations in dopamine signaling using multiple kinetic measures

JT Yorgason, RA Espaņa, SR Jones - Journal of neuroscience methods, 2011 - Elsevier
The fast sampling rates of fast scan cyclic voltammetry make it a favorable method for
measuring changes in brain monoamine release and uptake kinetics in slice, anesthetized, and …

The hypocretin–orexin system regulates cocaine self‐administration via actions on the mesolimbic dopamine system

RA Espaņa, EB Oleson, JL Locke… - European Journal of …, 2010 - Wiley Online Library
Recent evidence suggests that the hypocretin–orexin system participates in the regulation
of reinforcement processes. The current studies examined the extent to which hypocretin …

Hypocretin 1/orexin A in the ventral tegmental area enhances dopamine responses to cocaine and promotes cocaine self-administration

RA Espaņa, JR Melchior, DCS Roberts, SR Jones - Psychopharmacology, 2011 - Springer
… Consistent with this, SB-334867 attenuates cocaine-induced increases in both tonic and
phasic DA activity and reduces the effects of cocaine on DA uptake inhibition (Espaņa et al. …
