Abstract Neurons using serotonin (5-HT) as neurotransmitter and/or modulator have been
identified in the central nervous system in representatives from all vertebrate clades …

Recent investigations confirm the importance of nonsynaptic signal tranmission in several
functions of the nervous tissue. Present in various periventricular brain regions of …

The histaminergic system and its relationships to the other aminergic transmitter systems in
the brain of the zebrafish were studied by using confocal microscopy and …

The bony fishes consist of ray-finned fishes and lobe-finned fishes. In ray-finned fishes, the
forebrain forms a morphocline from the cladistian bichirs through teleosts regarding the …

Serotonin is a major central nervous modulator of physiology and behavior and plays
fundamental roles during development and plasticity of the vertebrate central nervous …

The effects of exogenous tryptophan on serum cortisol, glucose, lysozyme, alternative
complement pathway (ACH50), TSH, T 4 and T 3 responses before and after an acute stress …

All studies to date of cholinergic systems of bony fishes have been done in teleosts. To gain
further insight into the evolution of the cholinergic systems of bony fishes, we have studied …

In non‐mammalian vertebrates, serotonin (5‐HT)‐producing neurons exist in the
paraventricular organ (PVO), a diencephalic structure containing cerebrospinal fluid (CSF) …

Chondrychthyans (cartilaginous fishes) are key to understanding the ancestral gnathostome
condition since they provide an outgroup to sarcopterygians and actinopterygians. To gain …

Brain developmental disorders in humans, including Autism Spectrum Disorders (ASD) and
Down's syndrome, have been linked to increased serotonin levels. This work was designed …
