About
Karel Blahna’s research centers on the neurobiology of spatial navigation, fear learning, and sex differences in avoidance behavior. His major contributions include pioneering the “enemy avoidance” paradigm—a novel behavioral task in which a rat on a circular arena must evade a moving object (a small robot) while foraging. In a landmark study (2011, 40 citations), Blahna demonstrated that bilateral hippocampal inactivation with tetrodotoxin (TTX) severely disrupts performance in this task, providing direct causal evidence for the hippocampus’s role in dynamic spatial avoidance. This work bridges classic spatial memory research with ethologically relevant predator-prey scenarios. Expanding this paradigm, Blahna conducted a pioneering sex-differences study (2012, 10 citations), revealing that female rats exhibit more thigmotaxis, hypolocomotion, and fear-like reactions compared to males—findings that challenge assumptions about uniform spatial abilities and highlight the importance of sex as a biological variable. His work is notable for integrating robotics with behavioral neuroscience, creating reproducible, real-time avoidance challenges. With a focused yet impactful citation record, Blahna’s research offers a compelling model for studying hippocampal function, anxiety, and sex-specific strategies in spatial decision-making.
