Research Interests

The Middleton Lab research investigates the properties and function of neurons and synaptic connections in brain areas involved in sensory perception, stress response and pain modulation. These areas include neocortex, amygdala, periaqueductal gray (PAG) and lateral hypothalamus. Our goal is to characterize how neural circuits in these regions of interest function under normal physiological conditions and how their structure and function changes under conditions of external stressors, chronic substance exposure, chronic pain and/or traumatic brain injury. We use electrophysiological recording techniques and advanced computational analysis techniques to achieve this characterization. Additionally, we test the potential for existing and novel pharmacological therapeutics to protect and restore normal physiological function of neural circuits in these disease and neural insult states.
