Your brain contains billions of specialized cells called neurons that are the building blocks of your nervous system. When active, neurons generate electrical pulses and release chemical secretions to communicate with each other.
Neurons pass information at junctions called synapses - tiny gaps where the axon of one neuron connects with the dendrite of another. This process, called neurotransmission, is how your brain cells talk to each other through chemical and electrical signals.
Brain chemicals play crucial roles in neural communication. Hormones can excite neurons, inhibit them, or change their sensitivity to other signals. Neurotransmitters like acetylcholine help with attention, GABA provides pain relief, while others like dopamine, serotonin, and endorphins regulate everything from mood to movement.
Brain Buzz Did you know that your brain uses the same amount of power as a 10-watt light bulb? All those neurons communicating through neurotransmitters are incredibly energy-efficient!
Scientists study the brain using advanced techniques like fMRI, EEG, and PET scans to see which areas activate during different activities. Your brainstem, located deep in your brain, controls vital functions including breathing, heart rate, blood pressure, and sleep.
The brain has specialized hemispheres with different strengths. The left hemisphere handles analytical thinking, logic, language, and mathematical reasoning. The right hemisphere excels at holistic thought, intuition, creativity, and artistic expression. These hemispheres are connected by a bundle of nerves called the corpus callosum.
The brain has three main parts the forebrain, midbrain, and hindbrain. The forebrain includes the cerebrum (the largest part), thalamus, and hypothalamus. The cerebrum is responsible for conscious thought and voluntary actions and is divided into four lobes frontal, parietal, occipital, and temporal.
Quick Fact Your brain's left and right hemispheres aren't strictly divided in function—they work together constantly. The idea that people are "left-brained" or "right-brained" is mostly a myth!
The cerebrum makes up about 85% of your brain's weight and is the thinking powerhouse. It controls voluntary muscles, processes sensory information, and stores both short-term and long-term memories that make you who you are.
The limbic system is your brain's emotional center. It includes the thalamus (processes most sensory information), hypothalamus , amygdala (processes fear and emotion), and hippocampus (crucial for forming new memories and spatial navigation).
Your hindbrain contains the cerebellum or "little brain," which has its own hemispheres and folded surface. It coordinates movement, posture, and balance, allowing you to perform physical activities smoothly without conscious thought.
Mind-Blowing When the brain suffers damage, some fascinating conditions can occur. In contralateral neglect, usually from damage to the right parietal lobe, patients completely ignore everything on their left side—even their own body parts! Similarly, phantom limb syndrome causes amputees to feel sensations in limbs that are no longer there.
Brain and neurological conditions often resolve on their own as the brain has remarkable healing abilities. However, when symptoms persist, several treatment approaches can help restore function and reduce discomfort.
Doctors might prescribe medications like antidepressants or anticonvulsants to manage symptoms by regulating neurotransmitter activity. Many patients also benefit from non-pharmaceutical approaches like meditation, relaxation techniques, and biofeedback that help retrain brain patterns.
Alternative treatments can be surprisingly effective for certain conditions. These include hypnosis, acupuncture, massage, and regular exercise—all of which can influence how the brain processes signals and help establish new neural pathways.
Success Strategy Your brain shows incredible neuroplasticity—the ability to form new connections throughout life. This means you can continue learning, adapting, and recovering from injuries in ways scientists once thought impossible!

Unit 6 review
PsychologyStudy guide on chapter 8, theories on how people develop over a lifetime. Information was from the textbook Introduction to Psychology by Hawkes Learning and supplemented by my professor's resources.
PsychologyExplore the intricate processes of mitosis and meiosis, including key stages like prophase, metaphase, anaphase, and telophase. Understand the significance of crossing over, chiasmata, and independent assortment in genetic variation. This detailed summary covers the differences and similarities between mitosis and meiosis, highlighting their roles in cell division and reproduction.
PsychologyExplore Bowlby's monotropic theory of attachment, focusing on the internal working model, social releasers, and the impact of early relationships on parenting. This mind map covers key concepts such as secure and insecure attachment, the law of continuity, and the critical period for forming attachments. Ideal for students studying attachment theory and its implications in child development.
PsychologyExplore the findings of various studies on attachment types, including Jin (2012), Simonella (2014), and Van IJzendoorn & Kroonenberg (1988). This summary highlights the proportions of secure, insecure avoidant, and resistant attachments across different cultures, emphasizing the impact of cultural practices on attachment styles. Ideal for students studying attachment theory and its cultural implications.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend
