After the last few posts about my Neurobiology Master’s thesis, today I would like to follow up on the story of how I ended up doing a PhD in Germany and I will write about the first semester of my second and last year of Master’s. After that pretty hard first year, where I realized… Continue reading What is a prion?
Today I will talk again about the neuromodulators used by the brain (you can find a quick description of what a neuromodulator is here and a description of serotonin, oxytocin, adrenaline and dopamine by clicking on their names) and I will write about the neuropeptide Y (NPY), the most abundant neuropeptide in the brain that,… Continue reading Do we have an anxiolytic neuromodulator?
This week I will take a break from the “brain facts” category and, consequently, from the description of the different neuromodulators our brain use (you can find a quick description of what a neuromodulator is here and a description of serotonin, oxytocin, adrenaline and dopamine by clicking on their names) to talk about a “news… Continue reading What is the CAR-T therapy?
On this post I will continue writing about neurotransmitters (see this post for a quick explanation of the term neurotransmitter) and today I will focus on dopamine, a neurotransmitter involved in movement, or better, motor control (unfortunately, defects in the dopaminergic systems are well known by Parkinson patients and their families) as well as executive… Continue reading What about the “molecule of motivation”?
Following up on my neuromodulators topic (have a look at my previous posts about serotonin and oxytocin), today I will talk about the “stress” or “fight-or-flight” hormone: adrenaline. Experiencing a stressful event usually triggers the release of adrenaline, the “stress hormone”, that in turn produces well-orchestrated physiological changes. The stress response begins in the brain,… Continue reading What is the “fight-or-flight” response?
Following up on chemical messengers used by the brain and their modulators, today I will talk about oxytocin, the “love molecule”. Oxytocin is a neuromodulator, that is, as I already written on my previous post about serotonin, a molecule able to modulate the transmission of information among neurons. However, oxytocin is also a hormone (basically,… Continue reading What about the love molecule?
Another very interesting course that I attended during my first year of Neurobiology Master‘s was the one called “Neurochemistry and Neuropharmacology”. During this course, we finally started studying the different chemicals, called neurotransmitters, produced by neurons in the nervous system. As I have already written in an old post, neurons communicate through electricity and chemical… Continue reading How do benzodiazepines work?
As I have already anticipated last week, the differences in the central nervous system (CNS) among vertebrates was a very interesting course, so today I would like to talk about a byword for visual acuity, “hawk-eyed”, and why it is known that birds see better than humans. We use the catchword “hawk-eyed” as an adjective… Continue reading Why do we say “hawk-eyed”?
During my first year of Master’s degree in Neurobiology I had to face quite some striking challenges, that started already during the first semester. I actually had to go back to Physics and this time try to really understand it and apply it to what I have always wanted to study: the brain. As I… Continue reading Where is adult neurogenesis happening?
Eventually, after graduating with a bachelor’s in Biotechnology with an excellent vote, I could go on with my studies and I decided to continue staying at the University of Pavia and enrol in the Neurobiology master’s degree. As I already mentioned in one of my first posts, I always got fascinated by the complexity of… Continue reading Who are the fathers of Neuroscience?
