Adaptive integration of self-motion and goals in posterior parietal cortex
Autor: Andrew S. Alexander, Janet C. Tung, G. William Chapman, Allison M. Conner, Laura E. Shelley, Michael E. Hasselmo, Douglas A. Nitz
Publikováno v: Cell Reports, Vol 38, Iss 10, Pp 110504- (2022)
Summary: Rats readily switch between foraging and more complex navigational behaviors such as pursuit of other rats or prey. These tasks require vastly different tracking of multiple behaviorally significant variables including self-motion state. To

Neural responses in retrosplenial cortex associated with environmental alterations
Autor: Lucas C. Carstensen, Andrew S. Alexander, G. William Chapman, Aubrey J. Lee, Michael E. Hasselmo
Publikováno v: iScience, Vol 24, Iss 11, Pp 103377- (2021)
Summary: The retrosplenial cortex (RSC) is an area interconnected with regions of the brain that display spatial correlates. Neurons in connected regions may encode an animal’s position in the environment and location or proximity to objects or bou

Neuronal representation of environmental boundaries in egocentric coordinates
Autor: James R. Hinman, G. William Chapman, Michael E. Hasselmo
Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-8 (2019)
The hippocampus represents an allocentric map of space, however, motor movements used for navigation are defined in an egocentric framework. Here, the authors report that dorsomedial striatal neurons exhibit an egocentric representation of the bounda

Grass inflorescence and spikelet culture: An appraisal
Autor: G. P. Chapman
Publikováno v: Euphytica. 81:121-129
Techniques of inflorescence and spikelet culture have been used for three major cereals. In maize, the influence of hormones on sexuality has been demonstrated. For wheat and barley the influence of supplying carbohydrate and nitrogen on grain conten

In vitro normal and variant development of t'ef (Eragrostis tef) spikelets
Autor: H. Tefera, G. P. Chapman
Publikováno v: Plant Cell Tissue and Organ Culture (PCTOC). 31:233-237
Spikelets of t'ef, Eragrostis tef were cultured from the pre-anthesis stage to seed maturation, although only a small proportion of these seeds germinated to produce adult plants. A liquid culture medium originally formulated for wheat spikelets was

Alternative pathways in grass spikelet development
Autor: G. P. Chapman
Publikováno v: Plant Growth Regulation. 11:33-36
To the casual observer, one grass inflorescence looks very much like another and yet the family has diverged to nearly 800 genera and almost 10 000 species; is distributed worldwide and has become the centrepiece of agriculture. Such predominance can
