Fibrinolysis and the control of blood coagulation

JC Chapin, KA Hajjar - Blood reviews, 2015 - Elsevier
Fibrin plays an essential role in hemostasis as both the primary product of the coagulation
cascade and the ultimate substrate for fibrinolysis. Fibrinolysis efficiency is greatly influenced …

Sensorimotor encoding by synchronous neural ensemble activity at multiple levels of the somatosensory system

MAL Nicolelis, LA Baccala, RCS Lin, JK Chapin - Science, 1995 - science.org
Neural ensemble processing of sensorimotor information during behavior was investigated

Mapping the body representation in the SI cortex of anesthetized and awake rats

JK Chapin, CS Lin - Journal of Comparative Neurology, 1984 - Wiley Online Library
We have used single unit recording techniques to map the representation of cutaneous and
joint somatosensory modalities in the primary somatosensory (SI) cortex of both …

Progesterone alters GABA and glutamate responsiveness: a possible mechanism for its anxiolytic action

SS Smith, BD Waterhouse, JK Chapin, DJ Woodward - Brain research, 1987 - Elsevier
In this study, the neuromodulatory effects of progesterone were tested in an intact neuronal
