AbstractAsymmetries in motor behavior, such as human hand preference, are observed throughout bilateria. However, neural substrates and developmental signaling pathways that impose underlying functional lateralization on a broadly symmetric nervous system are unknown. Here we report that in the absence of over-riding visual information, zebrafish larvae show intrinsic lateralized motor behavior that is mediated by a cluster of 60 posterior tuberculum (PT) neurons in the forebrain. PT neurons impose motor bias via a projection through the epithalamic commissure to the habenula. Acquisition of left/right identity is disrupted by heterozygous mutations in mosaic eyes and mindbomb, genes that regulate Notch signaling. These results define the neuronal substrate for motor asymmetry in a vertebrate and support the idea that developmental pathways that establish visceral asymmetries also govern acquisition of left/right identity.

Humanism returns for the New Materialism in ‘nonhuman’ form as matter. New ‘matter’ and new materialism thus fashion the world to human advantage in the gesture of abjecting us. They commit us to the humanism of masochists. They offer an animistic and paradisiacal realm of immediate transactions, human to human, human to and with nonhuman, face to face, world without end. The impulse is tactically and strategically useful. But ‘matter’ will not help us if we fashion it so that it bears in its concept the signature of a human hand in its making. Can we do otherwise? Only by conceiving matter as what absolutizes what is not-one: matter from which no discipline will normally, normatively, produce an object or take its concept; on which heroical abjection will founder; matter non-human in ways the human animal can neither designate, nor ever count.
