This is an image of a brain cell (neuron). The cell body (spherical structure near the bottom) possess long branched processes, called dendrites. The two thick triangular shapes are electrodes to assess the electrical properties of the neuron.

Neurons integrate thousands of inputs from other neurons to generate behaviorally-relevant outputs. With my electrical recordings, I was trying to gain insight into the input-output transformation happening in this particular neuron. My long-term goal is to link the features of neurons with the brain operations that produce behavior.
