Converting color memory toward a spatial format to benefit behavior

This study shows that color memory benefits from spatial information when the response wheel is fixed, with faster response initiation and gaze bias toward anticipated spatial positions.

Top-down feedback can explain the existence of working memory traces in early visual cortex

This study shows that top-down feedback, not short-term synaptic plasticity, explains working memory traces in early visual cortex by enabling robust and selective memory storage.

Visual representations in the human brain rely on a reference frame that is in between allocentric and retinocentric coordinates

The paper investigates whether visual information in the human brain is represented in an allocentric or retinocentric reference frame using EEG and head tilt manipulations, finding an intermediate representation.

Model mimicry limits conclusions about neural tuning and can mistakenly imply unlikely priors

The paper critiques a method called 'generative forward modeling' used to infer neural tuning properties from EEG data, arguing it leads to unreliable conclusions due to model mimicry.

A gradual transition toward categorical representations along the visual hierarchy during working memory, but not perception.

The paper shows that during working memory, orientation representations in the visual hierarchy become more categorical compared to perception, with a gradual shift toward categorical formats in more anterior regions.

Flexible utilization of spatial- and motor-based codes for the storage of visuo-spatial information

The paper investigates how working memory reconfigures neural representations based on behavioral goals, showing reduced spatial coding in visual areas and increased motor coding when responses are known.

Manipulating attentional priority creates a trade-off between memory and sensory representations in human visual cortex

This study shows that focusing attention on sensory inputs during memory tasks reduces memory fidelity in early visual cortex, while ignoring distractors improves memory but reduces sensory representation fidelity.

Simultaneous representation of sensory and mnemonic information in human visual cortex

This study shows that human visual cortex can represent both working memory contents and new sensory inputs simultaneously at the population level.

Faded visual afterimages reappear after TMS over early visual cortex

This study uses TMS over early visual cortex to reverse visual fading of perceived hands, suggesting inhibitory processes in EVC can be modulated.

How Transcranial Magnetic Stimulation over Early Visual Cortex impacts short-term memory precision and guess rate

This study investigates how transcranial magnetic stimulation (TMS) over early visual cortex affects short-term memory precision and guess rate, finding enhanced memory precision at targeted retinotopic locations and increased guessing with early TMS pulses.
