Electric Forest
Semiconductors are materials that are used as switches in modern electronics. While the switches in your computer and smartphone are made of silicon, carbon-based organic semiconductors offer the potential for flexible, inexpensive electronics. Toward this goal, students in CHEM 100R have synthesized a novel organic semiconductor. For an organic semiconductor film to perform well, it must be processed so that is both crystalline and continuous. Students in CHEM 165 … Continue reading Electric Forest
Nanowires
Nanowires are thin structures measuring 0.000000001 meters in diameter, which is so thin that they essentially behave as if they only have one-dimension. This one-dimensional nature gives nanowires a ton of interesting electrical and magnetic properties, which are super useful in electronics and medical devices, especially as they are getting smaller and smaller. Nanowires can be made from a number of different materials. The grey columns in this … Continue reading Nanowires
Just Keep Swimming
When you read a research article, what you see is a finished product. Behind that finished product are countless hours, weeks, months, and likely years of time and effort that went into making that published article. Not only do the experiments take time, but so does setting up and troubleshooting all of the techniques that were used. In science, things rarely work the first time … Continue reading Just Keep Swimming
My Favorite Things
The orbitofrontal cortex (OFC) is an area of the brain located in the prefrontal cortex, which, as its name suggests, is the front part of the brain. The OFC is my favorite area of the brain, partially because it was the first region I studied, but mostly because of its complex role in motivated behaviors. The OFC is comprised of five subregions: medial, ventral, ventrolateral, … Continue reading My Favorite Things

The Nucleus Accumbens (NAc) is an area of the brain that is part of the Basal Ganglia system. It is divided into two subregions: the core and the shell. As you can imagine, the core region is nested within the shell. The NAc is primarily composed of neurons that contain GABA, the primary inhibitory neurotransmitter. These neurons make up ~95% of NAc neurons and contain … Continue reading Breaking Gad
Gad to the Bone
The Ventral Pallidum (VP) is an area of the brain that is part of the Basal Ganglia system. The VP is involved in regulating motivation and reward learning, connected with a variety of other brain regions, including another part of the Basal Ganglia called the Nucleus Accumbens (NAc). The NAc is also heavily implicated in motivation and reward learning, and a large part of the … Continue reading Gad to the Bone
Orange Crush
The Dorsal Raphe Nucleus, or DRN, is an area of the brain located along the midline of the brainstem that contains the largest number of serotonin containing (serotonergic) neurons in the brain. Serotonin participates in mood setting, sleep, social behavior, and many other things. Another cell type in this area are neurons that contain Glutamate Decarboxylase 1 (Gad1), which helps produce gamma-aminobutyeric acid (GABA), the … Continue reading Orange Crush
Sweet Serotonin
The Dorsal Raphe Nucleus, or DRN, is an area of the brain located along the midline of the brainstem, which is found towards the back of your brain. The DRN contains the largest number of serotonin-containing neurons, called serotonergic neurons, in the brain. You may recognize serotonin from the drug advertisements on TV, as it is a popular target for treating depression. Unsurprisingly, serotonin is … Continue reading Sweet Serotonin
Amygdala On My Mind
The amygdala is an area of the brain named for its almond shape (amygdala is Latin for almond). The amygdala is necessary for any biologically significant event, or anything related to survival, because of its involvement in decision-making, memory, and emotional responses, including both positive and negative. The amygdala is most commonly known for its role in aversive learning, in which a behavior is taught … Continue reading Amygdala On My Mind
