SMP Spotlight

Katie Gluskin and Jeff Haus present their SMP
Katie Gluskin and Jeff Haus, "Entorhinal Cortex Lesions, Habituation, and Latent Inhibition," 2013. Gluskin and Haus, the 2013 co-winners of the Neuroscience Award, infused a neurotoxin into the entorhinal cortex of rats to induce a lesion, and measured the resulting habituation and latent inhibition behavior within a fear conditioning paradigm.

Severino, Amie (2011).  Effects of ethanol on mechanoreceptor activity in the medicinal leech (Hirudo verbana). (Mentor: M. Baltzley)

Abstract 

Ethanol has diverse effects on the human nervous system. It has numerous effects on perception, sensation, behavior, and cognition. Knowing how ethanol affects invertebrate organisms helps understand its effects in humans. The majority of ethanol studies using invertebrates focus on motor effects, so the effects on sensation are less understood. Hirudo verbana, a type of medicinal leech, is an exceptional modeling system to examine the physiological effects of an acute, low-dose, ethanol exposure on the spontaneous firing patterns of mechanosensory cells. Action potential characteristics that may be altered by exposure of ethanol were examined in nociceptive (N) cells. The half-width of action potential afterhyperpolarizations were significantly increased by ethanol after the cell was exposed to ethanol and washed with saline. Though no other action potential characteristics were altered by exposure to ethanol, this finding is worth expanding research upon the subject of mechanosensory cell sensitivity to ethanol.
