Caffeinated plants provide an unforgettable experience.
Honeybees rewarded with caffeine remember the smell of specific flowers longer than bees given only sucrose, according to a study published in Science. “By using a drug to enhance memories of reward,” the study says, “plants secure pollinator fidelity and improve reproductive success.”
Many drugs used by humans come from plants. But what role do the drugs play for the plants themselves? Frequently, they play the role of toxic ave........ Read more »

As I mentioned before I worked in a rat lab, and over the next few weeks I'd like to write a bit about some of the research I did as a graduate student at UMSL. I spent my time depressing rats and treating some of them with novel plant-derived compounds (some poor rats just got depressed and given placebo). Before I can tell you more about my project I'd like to share with you some of the work that influenced me. "If I have seen further it is by standing on the shoulders of Giants ." -- Is........

A tamarin rock star (photographed by Ltshears at Wikimedia)Our moods change when we hear music, but not all music affects us the same way. Slow, soft, higher-pitched, melodic songs soothe us; upbeat classical music makes us more alert and active; and fast, harsh, lower-pitched, dissonant music can rev us up and stress us out. Why would certain sounds affect us in specific emotional ways? One possibility is because of an overlap between how we perceive music and how we perceive human voic........ Read more »

Back in 1993 this diagram was published, but the paper I am looking at was published in 1998 by Llinas and others (citation below); it contains the same diagram.

I've got a new post over on the SFARI (Simons Foundation Autism Research Initiative) blog discussing the use of control groups in autism research.Control groups are an essential part of autism research, providing a benchmark against which to assess those with autism. Finding, for instance, that participants with autism score an average of 68 percent on a test is meaningless if you don’t know how people who don’t have autism do on the same test. A control group can also b........ Read more »

The third (and final, at the moment) paper in the likelihood calculus series from Dr. Terrence Sanger is Distributed control of uncertain systems using superpositions of linear operators.

This is the paper that delivers on all the promises of building a controller out of a system described by the stochastic diff........ Read more »

Zoloft class action lawsuits are piling up, as more and more women who were told by doctors, who in turn were told by pharmaceutical giant Pfizer, the manufacturer of Zoloft – that the popular SSRI (selective serotonin reuptake inhibitor) antidepressant was safe to take during pregnancy, give birth to infants with potentially lethal defects.

Weaning off Zoloft, or any other SSRI (selective serotonin reuptake inhibitor) or SNRI (serotonin norepinephrine reuptake inhibitor) is no walk in the park.

Maureen O’Connor, former mayor of San Diego and heir to her late husband Robert O. Peterson’s Jack-in-the-Box fortune, won over $1 billion playing video poker over the course of 9 years (2000-2009), according to U-T San Diego. However, she lost an even greater amount during that time, resulting in a net gambling debt of $13 million. To cover some of these losses, she transferred $2 million from her husband's nonprofit foundation to her personal bank account. She was recently charged with m........ Read more »

Yes, researchers are finding that Prozac weight gain might occur more (metaphorically) in the brain than it does the body. While many people today remain obsessed with body image and weight loss, Prozac lists only the potential for Prozac weight loss, not Prozac weight gain, due to loss of appetite as one of the common [...]The post Prozac Weight Gain: It’s More in the Brain Than the Body appeared first on Life Mental Health.

I would like to thank my good friend Anonymous for asking me a great question on a previous post. Anonymous asks: "Are there any known transmitters in the NS that activate both inhibitory receptor subtypes AND excitatory receptor subtypes? Or does every known transmitter activate EITHER a bunch of excitatory subtypes OR a bunch of inhibitory subtypes?" (btw. This doesn't qualify as a LMAYQ post because it's a real true question that someone directly asked, not a search term)While I don'........ Read more »

FOXP2 is the poster child of a sexy gene. In songbirds, decreasing FOXP2 renders a bird incapable of mimicking their tutor, resulting in more variable song.

Serotonin syndrome – having too much serotonin in your system — conjures images of Serotonin syndrome symptoms–agitation, loss of coordination, nausea and vomiting as well as many other symptoms.

The concept “superiority illusion” refers to the fact that people tend to judge themselves as being superior to the average person when it comes to positive traits such as intelligence, desirability or other personality traits. This is mathematically not possible, because in a normally distributed population, most people cannot be above average. The “superiority illusion” belongs to a family of positive illusions, such as the “optimism bias”, which is characte........ Read more »

I've always been fascinated with the way the eye moves around a piece of art. Andrew Wyeth's "Christina's World" (or as I looked up "that painting of a girl in a field looking at a house")This piece by Andrew Wyeth is an obvious example of an artist completely controlling your gaze. There are pretty much no options here. You look at the girl and then you follow her gaze to the house. You probably then take a quick glance at that other house/barn to the left, and then maybe follow the edge of the........ Read more »
