Alzheimer's

Alzheimer's Poster

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, affecting approximately 47 million people worldwide. Updated in 2015, this poster summarizes the structural and functional changes observed in the progression of this neurodegenerative disease, as well as classic AD drug targets.

Learning & Memory

Learning & Memory Poster

Recognition memory enables us to make judgements about whether or not we have encountered a particular stimulus before. This poster outlines the cellular mechanisms underlying recognition memory and its links to long-term depression, as well as the use of pharmacological intervention to assess the role of neurotransmitters in recognition memory.

Pain

Pain Poster

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
