Host location in a specialist parasitoid wasp via olfactory cues – a physiological, behavioural and morphological study

, 2012
For successful host location, parasitoids are thought to have evolved different strategies to filter relevant olfactory cues which indicate the presence of the host. Because of their versatility in their ecology and behaviour, as well as their fine tuned

Visceral afferent pathways to the thalamus and olfactory tubercle: behavioral implications

Brain Research, 1998
The goal of this study was to support the hypothesis that visceral signals may integrate and influence behavior by way of direct pathways from the nucleus tractus solitarii (NTS) to the olfactory tubercle and the midline/intralaminar thalamus. An anterograde tracer, biotinylated dextran amine (BDA) was iontophoresed bilaterally into the caudal NTS to ...

Convulsant actions of 4-aminopyridine on the guinea-pig olfactory cortex slice [PDF]

, 1982
The effects of bath-applied 4-aminopyridine on neurones and extracellular potassium and calcium concentrations were recorded in slices of guinea-pig olfactory cortex. Neurones were orthodromically activated by stimulating the lateral olfactory tract.

Attentional modulation in human primary olfactory cortex

, 2005
International audienceCentral to the concept of attention is the fact that identical stimuli can be processed in different ways. In olfaction, attention may designate the identical flow of air through the nose as either respiration or olfactory ...

Brain evolution in bats (Mammalia, Chiroptera): auditory, Olfactory and Sensorimotor systems [PDF]

, 2002
Data for brain structure volumes was analysed using multiple regression to test for correlated volumetric evolution in bats (Mammalia, Chiroptera). Significant partial correlations were found between major brain subdivisions, and between structures ...

Brain-wide mapping reveals temporal and sexually dimorphic opioid actions

Communications Biology
The field of neuroscience has been transformed by recent advances in spatial mapping of neuronal activity across whole cleared brains. Rapid adoption of these techniques requires computational workflows that can facilitate experiments comparing multiple ...

Recruitment of specific dopamine neuron sub-circuits by opioids

Addiction Neuroscience
Opioids have strong addictive and rewarding effects, largely attributed to their interaction with the dopamine (DA) system. Within the ventral tegmental area (VTA), opioids increase DA neural activity by disinhibiting—or decreasing the tonic inhibition ...

Ultrastructural Characterization of Developmental Stages and Head Sensilla in Portici okadai, Vector of Thelazia callipaeda

Insects
Phortica okadai, a vector of Thelazia callipaeda, is associated with an increasing incidence of thelaziasis. The complex habitat and chemosensory system of P. okadai are critical for its proliferation and expansion.
