Dissociated representations of irritation and valence in human primary olfactory cortex

C Zelano, J Montag, B Johnson… - Journal of …, 2007 - journals.physiology.org
Irritation and negative valence are closely associated in perception. However, these
perceptual aspects can be dissociated in olfaction where irritation can accompany both …

JA Gottfried, R Deichmann, JS Winston… - Journal of …, 2002 - Soc Neuroscience
Studies of patients with focal brain injury indicate that smell perception involves caudal
orbitofrontal and medial temporal cortices, but a more precise functional organization has …

Connectivity of the amygdala, piriform, and orbitofrontal cortex during olfactory stimulation: a functional MRI study

A Nigri, S Ferraro, L D'Incerti, HD Critchley… - …, 2013 - journals.lww.com

Odor-evoked activity in the mouse lateral entorhinal cortex

W Xu, DA Wilson - Neuroscience, 2012 - Elsevier
The entorhinal cortex is a brain area with multiple reciprocal connections to the
hippocampus, amygdala, perirhinal cortex, olfactory bulb and piriform cortex. As such, it is …

Time course of odorant-induced activation in the human primary olfactory cortex

N Sobel, V Prabhakaran, ZUO Zhao… - Journal of …, 2000 - journals.physiology.org
Paradoxically, attempts to visualize odorant-induced functional magnetic resonance imaging
(fMRI) activation in the human have yielded activations in secondary olfactory regions but …

Hedonic-specific activity in piriform cortex during odor imagery mimics that during odor perception

M Bensafi, N Sobel, RM Khan - Journal of Neurophysiology, 2007 - journals.physiology.org
Although it is known that visual imagery is accompanied by activity in visual cortical areas,
including primary visual cortex, whether olfactory imagery exists remains controversial. Here …

Integrated neural representations of odor intensity and affective valence in human amygdala

JS Winston, JA Gottfried, JM Kilner… - Journal of …, 2005 - Soc Neuroscience
Arousal and valence are proposed to represent fundamental dimensions of emotion. The
neural substrates for processing these aspects of stimuli are studied widely, with recent …

[HTML][HTML] Cortical activity evoked by odors

DA Wilson, RL Rennaker - 2011 - europepmc.org
It has been hypothesized (Lynch 1986; Aboitiz et al. 2002; Montagnini and Treves 2003) that
the mammalian cortex initially evolved as an associative structure, allowing features of the …

Dissociated neural representations of intensity and valence in human olfaction

AK Anderson, K Christoff, I Stappen, D Panitz… - Nature …, 2003 - nature.com
Affective experience has been described in terms of two primary dimensions: intensity and
valence. In the human brain, it is intrinsically difficult to dissociate the neural coding of these …

Differences in the central-nervous processing of olfactory stimuli according to their hedonic and arousal characteristics

A Sorokowska, S Negoias, S Härtwig, J Gerber… - Neuroscience, 2016 - Elsevier
