Summary: The study investigates the impact of moment-by-moment fluctuations in arousal on orienting saccade responses. It suggests that small fluctuations in arousal, as indexed by pupil velocity, can modulate the saccade response evoked by SC microstimulation in awake behaving monkeys.

Summary: Smooth eye movements are essential for natural visual processes, and they can be guided by both visual cues and extraretinal signals. This study focuses on how the brain processes and integrates these signals during smooth pursuit eye movements. The researchers investigate the responses of neurons in the MSTd area of rhesus monkeys and find that most neurons have preferences for the direction of eye rotation based on both visual and extraretinal signals. This suggests that area MSTd plays a crucial role in integrating these signals and representing the velocity of smooth eye movements.

Summary: A systematic analysis reveals that the motor bursts in the superior colliculus (SC) neurons do not determine the kinematics of rapid eye movements. The spatial code and rate code of SC neurons exhibit dissociation, suggesting that saccade-related motor bursts in the SC do not necessarily dictate movement kinematics.

Summary: We can shift our gaze even when we focus internally on visual representations in working memory, including the movements of our head. In three virtual reality experiments, participants remembered 2 visual items and after a delay, their head movements were biased towards the location of the memorized item, despite there being no external item to orient towards. This heading-direction bias suggests a common neural circuitry involved in both internal and external orienting of attention.

Summary: The study investigates whether oculomotor behavior can be adapted based on post-saccadic target information alone. The results suggest that, based on post-saccadic information, eye movements and target localization can be adjusted to reduce errors, possibly indicating a continuous updating of the estimated pre-saccadic target location driven by postdictive motor error.

Summary: This study proposes a novel hypothesis that movement is triggered not only by an increase in firing rate but also by a reliable temporal pattern in the population response. It provides insights into motor preparation and generation by locating the movement gating signal in temporal features of activity in shared neural substrates. The findings highlight the importance of short-term population history in neuronal communication and behavior.

Summary: This paper addresses the problem of contour performance reduction caused by inaccurate contour error estimations. A novel tangential velocity tracking-based contouring control framework is proposed, which decouples the contour-following task in the tangential and normal directions of the reference contour and aims to track the desired tangential velocity commands at the foot point. By calculating the normal position tracking error, nearly perfect contour error estimation accuracy can be achieved.

Summary: Using natural scenes as a research method provides insights into the functioning of visual and eye movement systems in everyday life. This review examines the findings from behavioral and neurophysiological studies using natural scene viewing in humans and monkeys. The use of natural scenes for studying cerebral cortical activity is relatively new and poses challenges for data analysis. The article presents methods and results from using natural scenes to study the visual and eye movement cortex, highlighting new insights that this approach offers to enhance our understanding of these cortical regions compared to conventional methods.

Summary: The study reveals dynamic coding of choice information in SC-projecting M2 neurons during motor planning and execution, with disruption of this information impairing decision maintenance. Excitatory and inhibitory SC neurons both receive synaptic inputs from M2, but display differential temporal patterns in choice coding during behavior.

Summary: The study found that when an appropriate inter-stimulus interval is set between two-frame apparent motion stimuli, macaque monkeys' ocular following responses exhibit a reverse effect. This reverse effect persists for inter-stimulus intervals up to 160 ms, with virtually no eye movement response observed as the interval increases to longer durations. Additionally, longer exposure to the initial image decreases eye movement responses.

Summary: The study focuses on the brain network involved in autoscopic hallucination elicited by electrical stimulation of PVNH in a drug resistant epilepsy patient. The results demonstrate that electrical high frequency stimulation of PVNH mainly induces autoscopic hallucinations related to the face and upper trunk, while multi-modal connectivity analysis identifies the specific brain regions involved.

Summary: Direct electrical stimulation (DES) is crucial for mapping cortical function and treating drug-resistant epilepsy, with evidence also showing the importance of remote activations. Introducing a new stimulation paradigm and signal analysis methodology can disambiguate EEG responses and highlight the networks associated with clinical effects, providing valuable insights for invasive exploration and seizure propagation patterns.

Summary: Recording deep neuronal activity from structures such as the hippocampus using noninvasive techniques like magnetoencephalography (MEG) has been a challenge in neuroscience. This study successfully separated mesial activity and large-scale networks from MEG signals using blind source separation (BSS). Validated by intracerebral EEG signals, the study identified a mesial component in MEG signals during a memory task, confirming its origin in deep brain structures. This finding expands the potential of MEG in studying cognition and brain disorders.
