L’occhio quando fissa è fermo? Cosa sono i movimenti saccadici?

Il nostro occhio “vede nitidamente” solo in una piccolissima area all’interno della macula detta “fovea” per cui non sta mai fermo compiendo velocissimi micromovimenti (detti “movimenti sacca…

@marcwhoward oh I should clarify: my low prediction error is because I fully expect rich movement correlates brain wide, as we’ve seen with #corollarydischarge #activesensing especially #saccade related effects in #activevision. Movement initiation offers a path into the brains internal timing. Working back we can see ways in which neurons care more about their fellow neurons than they do about “the world out there”, and that sensing absent movement is more the exception than the rule. Animals are…animate. Plants….plant. Look at me all “brain inside out”. I try not to be too constructivist, but I Kant. No shade whatsoever to actually conducting the challenging experiments that measure and materialize this idea, and tell us more about how and where movement effects are seen!

Your eyes will #saccade 3-5 times per second while you read this, but what coordinates oculomotor & visual systems?

Do brain oscillations play a role?

Saccades are locked to the phase of alpha oscillations during natural reading

Saccades are locked to the phase of alpha oscillations during natural reading

We saccade three to five times per second when reading, but little is known about the neuronal mechanisms that coordinate the oculomotor and visual system. This study shows that alpha oscillations serve to time the processing between saccades and the visual system during natural reading.

What's the latest word on whether the FEF represents horizontal space more than vertical space?
