Neuromeric Distribution of Nicotinamide Adenine Dinucleotide Phosphate-Diaphorase Activity in the Adult Lamprey Brain

open access: yesFrontiers in Neuroanatomy, 2022
This study reports for the first time the distribution and morphological characterization of nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d; a reliable marker of nitric oxide synthase activity) positive elements in the central nervous ...

SEXUAL DIMORPHISM OF GLIAL FIBRILLARY ACIDIC PROTEIN (GFAP) IMMUNOREACTIVITY IN THE RAT INTERPEDUNCULAR NUCLEUS [PDF]

open access: yes, 2001
The intensity of immunostaining for the glial fibrillary acidic protein (GFAP) is outstandingly high in the interpeduncular nucleus. This nucleus was compared in males and females for its GFAP immunoreaction.

Griseum centrale, a homologue of the periaqueductal gray in the lamprey

open access: yesIBRO Reports, 2017
Fear, a response to threatening stimuli and important for survival, is a behavior found throughout the animal kingdom. One critical structure involved in the expression of fear-related behavior is the periaqueductal gray (PAG) in mammals, and in the ...

Understanding the habenula: A major node in circuits regulating emotion and motivation

open access: yesPharmacological Research, 2023
Over the last decade, the understanding of the habenula has rapidly advanced from being an understudied brain area with the Latin name ‘habena” meaning “little rein”, to being considered a “major rein” in the control of key monoaminergic brain centers ...

The pedunculopontine tegmental nucleus and the nucleus basalis magnocellularis : do both have a role in sustained attention? [PDF]

open access: yes, 2008
It is well established that nucleus basalis magnocellularis (NbM) lesions impair performance on tests of sustained attention. Previous work from this laboratory has also demonstrated that pedunculopontine tegmental nucleus (PPTg) lesioned rats make more ...

The interpeduncular nucleus regulates nicotineʼs effects on free-field activity

open access: yes, 1995
PARTIAL lesions were made with kainic acid in the interpeduncular nucleus of the ventral midbrain of the rat. Compared with sham-operated controls, lesions significantly (p < 0.25) blunted the early (< 60min) free- field locomotor hypoactivity caused by ...

Cholinergic and non-cholinergic forebrain projections to the interpeduncular nucleus

open access: yes, 1985
A combined fluorescent retrograde tracing and acetylcholinesterase (AChE) histochemical technique was used for the study of some forebrain projections to the interpeduncular nucleus (IPN).

Mapping neuronal inputs to Kiss1 neurons in the arcuate nucleus of the mouse.

open access: yesPLoS ONE, 2019
The normal function of the mammalian reproductive axis is strongly influenced by physiological, metabolic and environmental factors. Kisspeptin neuropeptides, encoded by the Kiss1 gene, are potent regulators of the mammalian reproductive axis by ...

EE2 and the Fish Brain: Age‐Dependent Impact of 17α‐Ethinylestradiol on Brain Cell Proliferation and Behavior in Sea Bass Larvae

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Endocrine‐disrupting chemicals (EDCs), such as 17α‐ethinylestradiol (EE2), have raised concerns about their potential effects on aquatic organisms, particularly during early developmental stages. In this context, the study of behavioral disruption has gained considerable attention, as it may have consequences on individual fitness and ...
