The Processing Characteristics of Bodily Expressions under the Odor Context: An ERP Study.

Behav Brain Res 2021 Jul 27:113494. Epub 2021 Jul 27.

School of Psychology, Shanghai University of Sport, Shanghai, 200438, China. Electronic address:

The recognition of facial expressions has been shown to be influenced by contextual odors. The aims of this study were (1) to investigate whether odor has a similar effect on the recognition of bodily expressions, and (2) to analyze the time-course of such effects. Sixty-nine adults were randomized into three groups to identify bodily expressions (happy, fearful, and neutral) in three odor environments (pleasant odor, unpleasant odor, and no odor). Read More

Feasibility of unilateral hemilaminectomy utilizing a Williams retractor for the resection of intradural-extramedullary spinal neoplasms.

Neurochirurgie 2021 Jul 27. Epub 2021 Jul 27.

Tufts University School of Medicine, 145 Harrison Ave, Boston, MA 02111, United States; Department of Neurosurgery, Tufts Medical Center, 800 Washington St, Box 178, Boston, MA 02111, United States. Electronic address:

Background: While open approaches have historically been used in the surgical treatment of intradural-extramedullary spine tumors, minimally-invasive surgical (MIS) techniques are frequently applied to minimize post-operative complications associated with open surgery. Tubular retractor systems in particular have been employed in combination with the unilateral hemilaminectomy (UHL) approach. Here we describe the use of a Williams retractor as a safe and effective minimally-invasive alternative to tubular retractor systems with similar post-operative outcomes. Read More

Quality of referrals for glaucoma assessment: a cross-sectional survey of clinical data and outcomes.

Int Ophthalmol 2021 Jul 30. Epub 2021 Jul 30.

Department of Ophthalmology, Lahey Hospital and Medical Center, One Essex Center Drive, Peabody, MA, 01960, USA.

Purpose: This study assessed the completeness of clinical information provided by ophthalmological and optometric referrals to glaucoma specialists consulting for open-angle glaucoma (OAG).

Methods: A retrospective, cross-sectional study of 72 internal referrals for evaluation of OAG in a multispecialty group practice was performed. The quality of the referral was assessed based on: (1) the completeness of the clinical triad of intraocular pressure measurement, visual field (VF), and cup-to-disk ratio for each eye; (2) the availability of the data necessary to calculate an ocular hypertension treatment study (OHTS) score; and (3) the presence of retinal nerve fiber layer (RNFL) imaging by mean of optical coherence tomography.

Authors:
Rob Gray

Optom Vis Sci 2021 Jul;98(7):738-749

Significance: This review evaluates model-based online approaches to visual-motor control in baseball batting in light of research studies on this topic.Throughout the history of research on baseball batting, there has been a presumptive winner in terms of how visual-motor control occurs for this complex skill.

Sensory coding and the causal impact of mouse cortex in a visual decision.

Elife 2021 Jul 30;10. Epub 2021 Jul 30.

UCL Queen Square Institute of Neurology, University College London, London, London, United Kingdom.

Correlates of sensory stimuli and motor actions are found in multiple cortical areas, but such correlates do not indicate whether these areas are causally relevant to task performance. We trained mice to discriminate visual contrast and report their decision by steering a wheel. Widefield calcium imaging and Neuropixels recordings in cortex revealed stimulus-related activity in visual (VIS) and frontal (MOs) areas, and widespread movement-related activity across the whole dorsal cortex.

Long-term stability of cortical ensembles.

Elife 2021 Jul 30;10. Epub 2021 Jul 30.

Department of Biological Sciences, Columbia University, New York, United States.

Neuronal ensembles, coactive groups of neurons found in spontaneous and evoked cortical activity, are causally related to memories and perception, but it still unknown how stable or flexible they are over time. We used two-photon multiplane calcium imaging to track over weeks the activity of the same pyramidal neurons in layer 2/3 of the visual cortex from awake mice and recorded their spontaneous and visually evoked responses. Less than half of the neurons were commonly active across any two imaging sessions. Read More

Expression and role of P-element-induced wimpy testis-interacting RNA in diabetic-retinopathy in mice.

World J Diabetes 2021 Jul;12(7):1116-1130

Department of Ophthalmology, Shengjing Hospital of China Medical University, Shenyang 110004, Liaoning Province, China.

Background: As one of the major microvascular complications of diabetes, diabetic retinopathy (DR) is the leading cause of blindness in the working age population. Because the extremely complex pathogenesis of DR has not been fully clarified, the occurrence and development of DR is closely related to tissue ischemia and hypoxia and neovascularization The formation of retinal neovascularization (RNV) has great harm to the visual acuity of patients.

Aim: To investigate the expression of P-element-induced wimpy testis-interacting RNA (piRNA) in proliferative DR mice and select piRNA related to RNV. Read More

The pictures who shall not be named: Empirical support for benefits of preview in the Visual World Paradigm.

J Mem Lang 2021 Dec 10;121. Epub 2021 Jul 10.

Dept. of Psychological and Brain Sciences University of Iowa.

A common critique of the Visual World Paradigm (VWP) in psycholinguistic studies is that what is designed as a measure of language processes is meaningfully altered by the visual context of the task. This is crucial, particularly in studies of spoken word recognition, where the displayed images are usually seen as just a part of the measure and are not of fundamental interest. Many variants of the VWP allow participants to sample the visual scene before a trial begins. Read More

Linear integration of sensory evidence over space and time underlies face categorization.

J Neurosci 2021 Jul 29. Epub 2021 Jul 29.

Center for Neural Science, New York University, New York, NY 10003, USA

Visual object recognition relies on elaborate sensory processes that transform retinal inputs to object representations, but it also requires decision-making processes that read out object representations and function over prolonged time scales. The computational properties of these decision-making processes remain underexplored for object recognition. Here, we study these computations by developing a stochastic multi-feature face categorization task. Read More

Quantitative assessment of atherosclerotic plaque, recent progress and current limitations.

J Cardiovasc Comput Tomogr 2021 Jul 16. Epub 2021 Jul 16.

Icahn School of Medicine at Mount Sinai, New York, NY, USA.

An important advantage of computed tomography coronary angiography (CCTA) is its ability to visualize the presence and severity of atherosclerotic plaque, rather than just assessing coronary artery stenoses. Until recently, assessment of plaque subtypes on CCTA relied on visual assessment of the extent of calcified/non-calcified plaque, or visually identifying high-risk plaque characteristics. Recent software developments facilitate the quantitative assessment of plaque volume or burden on CCTA, and the identification of subtypes of plaque based on their attenuation density. Read More
