This paper changed my life: ‘A massively parallel architecture for a self-organizing neural pattern recognition machine,’ by Carpenter and Grossberg

This paper taught me that we can use mathematical modeling to understand how neural networks are organized—and led me to a doctoral program in the department led by its authors.

What are recurrent networks doing in the brain?

The cortex is filled with excitatory local synapses, but we know little about their role in brain function. New experimental tools, along with ideas from artificial intelligence, are poised to change that.

NeuroAI: A field born from the symbiosis between neuroscience, AI

As the history of this nascent discipline reveals, neuroscience has inspired advances in artificial intelligence, and AI has provided a testing ground for models in neuroscience, accelerating progress in both fields.

Can an emerging field called ‘neural systems understanding’ explain the brain?

This mashup of neuroscience, artificial intelligence and even linguistics and philosophy of mind aims to crack the deep question of what "understanding" is, however un-brain-like its models may be.

Should we use the computational or the network approach to analyze functional brain-imaging data—why not both?

Emerging methods make it possible to combine the two tactics from opposite ends of the analytic spectrum, enabling scientists to have their cake and eat it too.

Dose, scan, repeat: Tracking the neurological effects of oral contraceptives

We know little about how the brain responds to oral contraceptives, despite their widespread use. I am committed to changing that: I scanned my brain 75 times over the course of a year and plan to make my data openly available.

Cracking the code of the extracellular matrix

Despite evidence for a role in plasticity and other crucial functions, many neuroscientists still view these proteins as “brain goop.” The field needs technical advances and a shift in scientific thinking to move beyond this outdated perspective.
