rTMS reduces cortical imbalance associated with visual hallucinations after occipital stroke

Rafique, S.A.; Richards, J.R.; Steeves, J.K.E. (2016-10)

Objective: To investigate the efficacy of multiday repetitive transcranial magnetic stimulation (rTMS) to the occipital cortex in a patient with continuous visual phosphene hallucinations for more than 2 years following ...

Own-age and own-sex biases in recognition of aged faces

Verdichevski, M; Steeves, J.K.E. (2013-10)

It is surprising how easily we are able to recognize people whom we have not seen in many years, somehow compensating for the aging-related facial changes that occurred. We measured the limits of the ability to recognize ...

Verdichevski, M; Steeves, J.K.E. (2013-10)

Evidence of multisensory plasticity: Asymmetrical medial geniculate body in people with one eye

Moro, S.S.; Kelly, K.R.; McKetton, L; Gallie, B.L.; Steeves, J.K.E. (NeuroImage: Clinical, 2015-10)

The medial geniculate body (MGB) plays a central role in auditory processing with both efferent and afferent tracts to primary auditory cortex. People who have lost one eye early in life have enhanced sound localization, ...

Consecutive TMS-fMRI reveals an inverse relationship in BOLD signal.

Mullin, C.R.; Steeves, J.K.E. (Journal of Neuroscience, 2013-12)

The human visual system is capable of recognizing an infinite number of scenes containing an abundance of rich visual information. There are several cortical regions associated with the representation of a scene, including ...

TMS to lateral occipital cortex disrupts object processing but facilitates scene processing.

Mullin, C.R.; Steeves, J (Journal of Cognitive Neuroscience, 2011-11)

The study of brain-damaged patients and advancements in neuroimaging have lead to the discovery of discrete brain regions that process visual image categories, such as objects and scenes. However, how these visual image ...

Behavioural and neuroimaging evidence for a contribution of color and texture information to scene classification in a patient with visual form agnosia.

Steeves, J.K.E.; Humphrey, G.K.; Culham, J.C.; Menon, R.S.; Milner, A.D.; Goodale, M.A. (Journal of Cognitive Neuroscience, 2004-03)

A common notion is that object perception is a necessary precursor to scene perception. Behavioral evidence suggests, however, that scene perception can operate independently of object perception. Further, neuroimaging has ...

Altered white matter connectivity associated with visual hallucinations following occipital stroke

Rafique, S.A.; Richards, J.R.; Steeves, J.K.E. (Brain and Behavior, 2018-05)

Introduction Visual hallucinations that arise following vision loss stem from aberrant functional activity in visual cortices and an imbalance of activity across associated cortical and subcortical networks subsequent ...

TMS to the TOS impairs scene but not object categorization

Ganaden, R; Mullin, C.R.; Steeves, J.K.E. (Journal of Cognitive Neuroscience, 2013-06)

Traditionally, it has been theorized that the human visual system identifies and classifies scenes in an object-centered approach, such that scene recognition can only occur once key objects within a scene are identified. ...

Altered anterior visual system development following early monocular enucleation

Kelly, K.R.; McKetton, L; Schneider, K.A.; Gallie, B.L.; Steeves, J.K.E. (NeuroImage: Clinical, 2014)

Purpose Retinoblastoma is a rare eye cancer that generally occurs before 5 years of age and often results in enucleation (surgical removal) of the cancerous eye. In the present study, we sought to determine the consequences ...

Altered brain morphology following long-term survival from early monocular enucleation.

Kelly, K.R.; DeSimone, K; Gallie, B.L.; Steeves, J (NeuroImage: Clinical, 2015)

Purpose Retinoblastoma is typically diagnosed before 5 years of age and is often treated by enucleation (surgical removal) of the cancerous eye. Here, we sought to characterize morphological changes of the cortex following ...

Victimization and Perpetration Experiences of Adults with Autism

Weiss, Jonathan A.; Fardella, Michelle A. (Frontiers Media, 25/05/2018)

This study aimed to describe the self-reported experiences of childhood and adult victimization and perpetration in adults with autism spectrum conditions (ASC) compared to a matched sample, and how victimization and ...

Infant Clinical Pain Assessment: Core Behavioural Cues

DiLorenzo, Miranda; Pillai Riddell, Rebecca; B. Flora, David; D. Craig, Kenneth (The Journal of Pain, 2018)

Diverse behavioral cues have been proposed to be useful cues in infant pain assessment, but there is a paucity of evidence on the basis of formal psychometric evaluation to establish their validity for this purpose. We ...

Developing a Measure of Distress-Promoting Parent Behaviours During Infant Vaccination: Assessing Reliability and Validity

Pillai Riddell, Rebecca; Gennis, Hannah; Tablon, Paula; Greenberg, Saul; Garfield, Hartley (Canadian Journal of Pain, 2018)

Background: Infants rely on their parents’ sensitive and contingent soothing to support their regulation from pain-related distress. However, despite being of potentially equal or greater import, there has been little focus ...
