A matter of availability: sharper tuning for memorized than for perceived stimulus features
Our visual environment is relatively stable over time. An optimized visual system could
capitalize on this by devoting less representational resources to objects that are physically …

[HTML][HTML] Electrophysiological aftereffects of high-frequency transcranial random noise stimulation (hf-tRNS): an EEG investigation
There is evidence that high-frequency transcranial random noise stimulation (hf-tRNS) is
effective in improving behavioural performance in several visual tasks. However, so far there …

Visual stimulation induces distinct forms of sensitization of On-Off direction-selective ganglion cell responses in the dorsal and ventral retina
Experience-dependent modulation of neuronal responses is a key attribute in sensory
processing. In the mammalian retina, the On-Off direction-selective ganglion cell (DSGC) is …
