Chronic unit recording experiments conducted over the past two decades have identified many functional classes of neurons with saccade-related activity that reside in a host of brainstem nuclei. Older models of the saccadic system were based upon the properties of only a few of these functional types of neurons. They described the putative flow of signals through the brainstem circuitry and spe...

BACKGROUND Although termites are considered as agricultural pests, they play an important role in maintaining the ecosystem. Therefore, it matters to investigate the farmers' perception of the impacts of the termites on the agriculture and their indigenous utilization. METHODS A semi-structured questionnaire was used to interview 94 farmers through 10 villages of Atacora department, in the no...

Regarding van den Bedem, Schutte, van der Helm, and Simonsz: Mechanical properties and functional importance of pulley bands or ÔFaisseaux TendineuxÕ q In their paper entitled ''Mechanical properties and functional importance of pulley bands or ÔFaisseaux Tendi-neuxÕ, van den Bedem et al. (Vision Research 45 (2005) 2710–2714) argue that mechanical properties of connective tissues they define as...

Testing the hypothesis that the lateral cerebellum forms a sensory representation of arm movements, we investigated cortical neuronal activity in two monkeys performing visually-guided step-tracking movements with a manipulandum. A virtual target and cursor image were viewed co-planar with the manipulandum. In the normal task, manipulandum and cursor moved in the same direction; in the mirror t...

49 50 Visual working memory (VWM) helps to temporarily represent information from the 51 visual environment, and is severely limited in capacity. Recent work has linked various 52 forms of neural activity to the ongoing representations in VWM. One piece of evidence 53 comes from human event-related potential studies which find a sustained contralateral 54 negativity during the retention period ...

29 Sensorimotor impairments are common in ASD, but they are not well understood. 30 Here, we examined force control during initial pulses and the subsequent rise, sustained, 31 and relaxation phases of precision gripping in 34 individuals with ASD and 25 healthy 32 controls. Participants pressed on opposing load cells with their thumb and index finger 33 while receiving visual feedback regardin...

Laboratory studies were conducted to determine factors that affect the tunneling behavior of the western subterranean termite (Reticulitermes hesperus Banks). Soil particle sizes between 2.36 and 0.84 mm prevented tunneling. Exposure to solid layers of calcium, magnesium, or zinc borate did not repel workers, but produced >87 percent kill within 10 d. No tunneling occurred in soils treated with...
