[New chromosome abnormality in chronic myeloid leukemia].
A case of chronic myelogenous leukemia with myelofibrosis and failure to respond to busulfan therapy has been reported. An abnormal clone with a rearrangement of four chromosomes, 46, XX, t(1;9) (q21; q24), t(6;22) (q26;q11) was observed. The possible significance of these chromosome abnormalities which are different from the t(9;22) translocation in C.M.L. is discussed.

A centrifugally controlled circuit in the avian retina and its possible role in visual attention switching.
The isthmo-optic nucleus (ION) is the main source of efferents to the retina in birds. Isthmo-optic neurons project in topographical order on amacrine cells in the ventral parts of the retina, and a subclass of these known as proprioretinal neurons project onto the dorsal retina. We propose that, through the intermediary of the amacrine target cells, activity in the isthmo-optic pathway excites ganglion cells locally in the ventral retina but inhibits those in dorsal regions. This circuit would thereby mediate centrifugally controlled switches in attention between the dorsal retina, involved in feeding, and the more ventral parts, involved in scanning for predators. This hypothesis accounts for a wide range of disparate data from behavior, comparative anatomy, endocrinology, hodology, and neurophysiology.
