Experimental design and task. Top left: Intracranial electroencephalographic activity, eye and body movements were recorded as participants freely walked around the room. Wall-mounted motion-tracking cameras recorded the position of on-body reflective markers. Participants also wore an eye-tracking headset to monitor saccadic eye movements. A snapshot from the eye-facing camera is shown in the bottom right. For illustrative purposes, an experimenter is shown wearing the full setup. Top right: MRI of an example participant with an implanted RNS System. Purple dots indicate the location of four electrode contacts in the left medial temporal lobe (MTL). The top left inset shows an X-ray used to localize electrode positions. Bottom left: The environment contained 20 visible wall-mounted signs and three invisible circular target locations (0.7 m diameter). At the start of the task, participants freely explored the room to locate the invisible targets; each time a target was reached, an auditory tone signaled success, allowing them to gradually learn and remember these locations through experience. The task then alternated between two conditions: “visually-cued” navigation, during which participants navigated to a wall-mounted sign (e.g., “Blue 3”), and “memory-cued” navigation, during which they recalled and navigated to the previously learned invisible targets (e.g., “T”).

Wednesday vibes hit different when Saccades drops "Older Than Tomorrow" into the mix. Sometimes the best tracks come from artists you've never heard of but instantly need more from 🎵

Testing for trans-saccadic prediction error signaling by foveal SC neurons. Top: Monkeys generated a delayed, visually-guided saccade towards an extrafoveal target. The authors used a delayed paradigm to make sure that there was a stable visual image upon saccade generation. In some trials, the saccade target was unchanged throughout the whole trial (high spatial frequency grating embedded within a circular patch for this shown example). In other trials, they detected saccade onset and immediately flipped the saccade target to another feature (from a low to a high spatial frequency texture in the shown example). Bottom: The authors only selected foveal SC neurons with response fields (RF’s) not extending towards the pre-saccadic extrafoveal stimulus location. In this example, the RF was almost entirely contained within <2 deg eccentricity. Each black dot is a stimulus onset location during RF mapping, and the white circle (3 deg radius) shows the extent of the saccade target if it was perfectly foveated post-saccadically. The target covered the RF post-saccadically but not pre-saccadically. The z-axis indicates the visual response strength of the neuron at each stimulus location.

Why don't #saccades disrupt our continuous #visual experience? This study shows that neurons of the #SuperiorColliculus are sensitive to the pre-movement peripheral appearance of the eye movement targets, potentially explaining the experienced perceptual stability @plosbiology.org 🧪 plos.io/44cxQIe

Wonderful idea! 👀🧠 #neuroscience #saccades

Receptive-field Remapping and Space Representation Across Saccades AbstractThe nature and function of perisaccadic receptive-field (RF) remapping have been controversial. We used a delayed saccade task to reduce previous confounds and examined the remapping time…

Saccade - Wikipedia

People read in #Saccades

We have to #design for that.

Literally no-one reads everything you write.

Their eyes jump about all over the place.

And our brains just make words up based on shapes and outlines.

https://en.wikipedia.org/wiki/Saccade

(2/3)Together with colleagues from @mpfneuro.bsky.social, researchers from our @kerrlab.bsky.social reconstructed what predatory mammals see when they chase prey. They discovered that #saccades align the retina to world motion and not the actual thing they are chasing.

It was a weird year so don't come after me. But it was also the year I fell in love with Saccades, an offshoot of my favorite band The KVB.

Οι #σακκαδικές κινήσεις των οφθαλμών (οι ακούσιες γρήγορες κινήσεις που κάνουν τα #μάτια μας καθώς «σκανάρουμε» το περιβάλλον γύρω μας) γίνονται πιο αργές και λιγότερο ακριβείς στα άτομα με #Αλτσχάιμερ. Μια νέα #τεχνολογία έρχεται για να ανιχνεύσει έγκαιρα αυτή την αλλαγή. #Alzheimer #eyes #saccades
