Looking for inspiration for the undergrad Art in Neuroscience competition? Check out last year's winner, by Eve Dickerson, senior neuro major from Ohio State University. It's called Beneath the Surface. Read more about Eve's work and see the runnersup here: drive.google.com/file/d/1H7vU...
Digital art work featuring a human head outline with image of an iceberg inside. A brain is shown as part of the top of the iceberg with various pills, a cigarette and alcohol poured on it. The bottom of the ice berg has more drug imagery, barbed wire, distorted/pained human faces and a noose. The head is surrounded by outreached human hands.

Spotlight: Are you sleeping well nowadays? Sleep is an integral part of our #circadianrhythm. Organisms that don't sleep also show biological rhythms, even bacteria! Learn more in Ch 15 Biological Rhythms & Sleep by @mahoneymeg.bsky.social & @docofclocks.bsky.social tinyurl.com/itobnc15
Top is a diagram of a sagittal human brain with projections from the TMN (histamine), raphe nucleus (5HT), locus coeruleus (NE) in brainstem. Projections extend widely throughout the cortex. LDT/PPT (ACh) sends projections to the thalamus. Bottom shows a cartoon of a balance with VLPO/sleep on one side and TMN, Rn, LC and PPT/LDT with Wake on the other side. Sleep transitions are regulated by this 'flip flop switch'.

Spotlight: Drugs can powerfully change the brain. Sometimes this is a medical miracle, relieving pain or anxiety. But too much of any drug can be toxic and some drugs lead to addiction. Learn more in Ch14 Psychopharmacology by Dr. @shivonrobinson.bsky.social! tinyurl.com/itobnch14
Cartoon representations of drugs being administered intravenously (1min), intranasally (1-2 min), via inhalation (1-2 min), orally (20min-1hr) and transdermal (hours)Graph of plasma concentration (ng/L, y axis) versus time (hours). 3 curves show the plasma concentration of a drug over time for low, middle and high dose, revealing different absorption rates. Only the middle curve shows plasma concentrations within the therapeutic range (above “ineffective”) without inducing toxic effects.

Spotlight: Exams. Deadlines. Traffic. Feeling stressed yet? There is fascinating neuroscience behind stress. And many misconceptions too. Some stress is actually beneficial, for ex. Learn all about it in Ch 12 Stress by S. Muroy, MJ Ko, H Jaques &D Kaufer! #neuroscience #stress tinyurl.com/itobnch12
A line graph with y axis “behavioral performance” from low to high and x-axis “stress/stimulation” from too little to too much. An inverted-U curve is plotted. At too little stress, symptoms listed are impaired attention, boredom, confusion, apathy. In the middle, at the peak of the U, is eustress with symptoms focused attention, emotional regulation, rational thinking. At too much stress is distress, with symptoms of impaired memory, burn out, impaired executive functions.

Bottom: A series of 5 panels, each showing a drawing of a cross-section of skin with a different major touch/pain receptor shown in its anatomical position. A figure caption reads: Figure 9.2 Mechanoreceptory types. In this example from the skin, there aer Merkel disks and Meissner's corpuscles in the superficial part of the skin. Hair follicles, Ruffini endings and Pacinian corpuscles sit in the deeper part of the skin. All of these use large myelinated A-beta fibers. Unmyelinated C fiber Free nerve endings are found throughout the skin.

Spotlight: Ever noticed that food loses flavor when you have a cold. What's up with that? Your perception of flavor is not one sense. It is a mixing of taste, smell and chemosensation. Read about it in Ch8 Chemical Senses by Joe Zak & @jakesaunders.bsky.social tinyurl.com/itobnch8 #neuroscience
The left panel of this image shows the side view of a person’s face with a cup containing a beverage underneath the nose. The image shows how the aroma of the beverage passes through the nasal cavity. The right panel shows a detailed ultrastructure of the olfactory bulb. A textbox reads: Odorant molecules activate receptors in the cilia of olfactory sensory neurons. Olfactory sensory neuron axons cross into the olfactory bulb, synapsing on mitral cells in polysynaptic structures called glomeruli.
