Challenges and Approaches in the Study of Neural Entrainment

Author(s): Duecker K; Doelling KB; Breska A; Coffey EBJ; Sivarao DV; Zoefel B;

When exposed to rhythmic stimulation, the human brain displays rhythmic activity across sensory modalities and regions. Given the ubiquity of this phenomenon, how sensory rhythms are transformed into neural rhythms remains surprisingly inconclusive. An influential model posits that endogenous oscillations entrain to external rhythms, thereby encoding envi ...

Strategies used during the cognitive evaluation of older adults with dual sensory impairment: a scoping review

Author(s): Dumassais S; Pichora-Fuller MK; Guthrie D; Phillips NA; Savundranayagam M; Wittich W;

Background: Dual sensory impairment (DSI), the combination of visual and hearing impairments, is associated with increased risk for age-related cognitive decline and dementia. Administering cognitive tests to individuals with sensory impairment is challenging because most cognitive measures require sufficient hearing and vision. Considering sensory limita ...

Danger Changes the Way the Brain Consolidates Neutral Information; and Does So by Interacting with Processes Involved in the Encoding of That Information

Author(s): Omar A Qureshi

This study examined the effect of danger on consolidation of neutral information in two regions of the rat (male and female) medial temporal lobe: the perirhinal cortex (PRh) and basolateral amygdala complex (BLA). The neutral information was the association that forms between an auditory stimulus and a visual stimulus (labeled S2 and S1) across their pai ...

Electroencephalographic characteristics of children and adolescents with chronic musculoskeletal pain

Author(s): Ocay DD; Teel EF; Luo OD; Savignac C; Mahdid Y; Blain-Moraes S; Ferland CE;

Introduction: The pathophysiology of pediatric musculoskeletal (MSK) pain is unclear, contributing to persistent challenges to its management. Objectives: This study hypothesizes that children and adolescents with chronic MSK pain (CPs) will show differences in electroencephalography (EEG) features at rest and during thermal pain modalities when compared ...

Calcium activity is a degraded estimate of spikes

Author(s): Hart EE; Gardner MPH; Panayi MC; Kahnt T; Schoenbaum G;

Recording action potentials extracellularly during behavior has led to fundamental discoveries regarding neural function-hippocampal neurons respond to locations in space,1 motor cortex neurons encode movement direction,2 and dopamine neurons signal reward prediction errors3-observations undergirding current theories of cognition,4 movement,5 and learning ...

A Newly Identified Impairment in Both Vision and Hearing Increases the Risk of Deterioration in Both Communication and Cognitive Performance

Author(s): Guthrie DM; Williams N; Campos J; Mick P; Orange JB; Pichora-Fuller MK; Savundranayagam MY; Wittich W; Phillips NA;

Vision and hearing impairments are highly prevalent in adults 65 years of age and older. There is a need to understand their association with multiple health-related outcomes. We analyzed data from the Resident Assessment Instrument for Home Care (RAI-HC). Home care clients were followed for up t ...

Understanding Associative Learning Through Higher-Order Conditioning

Author(s): Gostolupce D; Lay BPP; Maes EJP; Iordanova MD;

Associative learning is often considered to require the physical presence of stimuli in the environment in order for them to be linked. This, however, is not a necessary condition for learning. Indeed, associative relationships can form between events that are never directly paired. That is, associative learning can occur by integrating information across ...

Anterior cingulate neurons signal neutral cue pairings during sensory preconditioning

Author(s): Hart EE; Gardner MPH; Schoenbaum G;

Of all frontocortical subregions, the anterior cingulate cortex (ACC) has perhaps the most overlapping theories of function.1-3 Recording studies in rats, humans, and other primates have reported diverse neural responses that support many theories,4-12 yet nearly all these studies have in common tasks in which one event reliably predicts another. This lea ...

Bioprinting of Adult Dorsal Root Ganglion (DRG) Neurons Using Laser-Induced Side Transfer (LIST)

Author(s): Roversi K; Ebrahimi Orimi H; Falchetti M; Lummertz da Rocha E; Talbot S; Boutopoulos C;

Cell bioprinting technologies aim to fabricate tissuelike constructs by delivering biomaterials layer-by-layer. Bioprinted constructs can reduce the use of animals in drug development and hold promise for addressing the shortage of organs for transplants. Here, we sought to validate the feasibility of bioprinting primary adult sensory neurons using a newl ...

Mechanisms of higher-order learning in the amygdala

Author(s): Gostolupce D; Iordanova MD; Lay BPP;

Adaptive behaviour is under the potent control of environmental cues. Such cues can acquire value by virtue of their associations with outcomes of motivational significance, be they appetitive or aversive. There are at least two ways through which an environmental cue can acquire value, through first-order and higher-order conditioning. In first-order con ...
