Oculomotor strategy of an avian ground forager: tilted and weakly yoked eye saccades.

Tyrrell LP1, Butler SR2, Fernández-Juricic E2.
The Journal of experimental biology.J Exp Biol.2015 Aug;218(Pt 16):2651-7. doi: 10.1242/jeb.122820. Epub 2015 Jul 2.
Many bird species are capable of large saccadic eye movements that can result in substantial shifts in gaze direction and complex changes to their visual field orientation. In the absence of visual stimuli, birds make spontaneous saccades that follow an endogenous oculomotor strategy. We used new ey

Goal-directed movements, such as pointing and saccades, have been shown to share similar neural architectures, in spite of the different neuromuscular systems producing them. Such structure involve an inverse model of the actuator being controlled, which produces the commands innervating the muscles

Large variability between individual response times, even in identical conditions, is a ubiquitous property of animal behavior. However, the origins of this stochasticity and its relation to action decisions remain unclear. Here we focus on the state of the perception-action network in the pre-stimu

現在までの認知的脳機能に関する研究では,主に課題中の刺激や事象に対する神経活動に焦点が当てられてきた.しかし,自発発火時の神経活動を調べることで,脳に潜在する構造的機能特性を知ることができるという研究成果が近年報告されている.本研究では,視覚誘導性眼球運動課題中の固視期間において,サルの後頭頂葉ニューロンの自発活動の時間相関を調べることにより,ニューロン固有の発火頻度保持特性を定量的に評価した.ま …
