Studying biological psychology in Year 10 is really important for a few reasons:

1. Understanding the Brain:

   • The brain has about 86 billion tiny cells called neurons. These neurons help shape our behavior and how we think.

2. What are Neurotransmitters?:

   • Neurotransmitters are special chemicals in our brain, like dopamine and serotonin. They help control our moods. If these chemicals are not balanced, it can lead to problems that affect 1 out of 4 people worldwide.

3. How the Nervous System Works:

   • The central nervous system (CNS) is responsible for processing all the information we get from the world. The brain manages around 100 billion cells to help us do this.

4. Building a Base for More Learning:

   • Learning about biological psychology gives students a strong foundation. This knowledge helps them understand psychological disorders and treatments, which are very important since the UK spends £22 billion every year on mental health services.

These key ideas help us see how our biology plays a big role in our behavior and mental processes.
