Numerosity adaptation suppresses early visual responses Open
Humans and many other animals possess an innate ability to rapidly perceive numerosity: the number of objects in a visual scene. Numerosity perception is influenced by adaptation, whereby previously viewed numerosities affect perception of…

Numerosity adaptation suppresses early visual responses Open
Humans and many animals rapidly and accurately perceive numerosity, the number of objects, in a visual image. The numerosity of recently viewed images influences our perception of the current image’s numerosity: numerosity adaptation. How …

Transitions from monotonic to tuned responses in recurrent neural network models during timing prediction Open
The brain exhibits a gradual transition in responses to visual event duration and frequency through the visual processing hierarchy: from monotonically increasing to timing-tuned responses. Over their hierarchies, properties of both respon…

Cortical quantity representations of visual numerosity and timing overlap increasingly into superior cortices but remain distinct Open
Many sensory brain areas are organized as topographic maps where neural response preferences change gradually across the cortical surface. Within association cortices, 7-Tesla fMRI and neural model-based analyses have also revealed many to…

Adaptation to numerosity changes monotonic responses of early visual cortex Open
Humans and many animals can perceive numerosity, the number of visual objects. Recently-viewed numerosities can influence numerosity perception and cause numerosity adaptation aftereffects. In the brain, numerosity produces both early visu…

Cortical quantity representations of visual numerosity and timing overlap increasingly but remain distinct Open
Numerical and temporal quantity estimations show behavioral commonalities, like adhering to Weber’s law. They also portray behavioral interactions, such that the duration of relatively low or high numerical values are perceived to be short…

Tuned responses to visual short-term memory load in a frontoparietal topographic map hierarchy Open
Visual short-term memory (VSTM), intentionally remembering image features, relies on interacting sensory and executive processes. Sensory processing relies on tuned responses, organized in hierarchical networks of topographic maps. How doe…

Mechanisms of speed encoding in the human middle temporal cortex measured by <span>7T fMRI</span> Open
Perception of dynamic scenes in our environment results from the evaluation of visual features such as the fundamental spatial and temporal frequency components of a moving object. The ratio between these two components represents the obje…

Attention drives human numerosity selective responses Open
Introduction Numerosity, the set size of a group of items, helps guide behaviour and decisions. Previous studies have shown that neural populations respond selectively to numerosities. How numerosity is extracted from the visual scene is a…

Visual timing-tuned responses in human association cortices and response dynamics in early visual cortex Open
Quantifying the timing (duration and frequency) of brief visual events is vital to human perception, multisensory integration and action planning. For example, this allows us to follow and interact with the precise timing of speech and spo…

Numerosity tuning in human association cortices and local image contrast representations in early visual cortex Open
Human early visual cortex response amplitudes monotonically increase with numerosity (object number), regardless of object size and spacing. However, numerosity is typically considered a high-level visual or cognitive feature, while early …

Linked changes in visual acuity, cortical population receptive field size, visual field map size, and retinal thickness in healthy human aging Open
Healthy human aging is associated with a deterioration of visual acuity, retinal thinning, visual field map shrinkage and increasing population receptive field sizes. Here we ask how these changes are related to each other in a cross-secti…

Topographic maps representing haptic numerosity reveals distinct sensory representations in supramodal networks Open
Dedicated maps for cognitive quantities such as timing, size and numerosity support the view that topography is a general principle of brain organization. To date, however, all of these maps were driven by the visual system. Here, we ask w…
