Chosen as  one of the best science books to read in 2021 by New Scientist, Overloaded explores how the chemicals in our brains control every aspect of our lives, from motivation to pain, mood to memory. 

 

I have always been curious, wanting to understand why and how the things around me work, but it wasn’t until university that I discovered my fascination with brain science. Here was a real challenge. An incredibly complex system, full of mysteries and unknowns, that needed breaking down, and understanding at the most fundamental level. And not only that, but it was something that affected us all, every day, and could answer perhaps the most fundamental question of all: why do we behave the way we do? 

 

In Overloaded, I explore all these complex interactions between our brain matter and the chemicals it bathes in and how they touch every aspect of our lives. From what we remember, how we make decisions and who we love; to basic survival drives such as hunger, fear and sleep. The book is crammed full of fascinating stories from scientists at the cutting-edge of research into the world of brain chemistry, who are uncovering the unexpected connections between these crucial chemicals that control us.

Getting enough sleep is vital for health and wellbeing. Unfortunately, it’s not always easy to do. While we don’t understand it fully, scientists are starting to pick apart the networks involved in sleep. And the beginnings of this understanding goes back to the First World War, and a strange illness known as Sleepy Sickness...

Reviews

In Overloaded, Ginny Smith gives a light, entertaining view of the way that the chemicals that act both as messengers and controls in the brain influence our behaviour, feelings, memory and more. Smith's writing style is conversational and fun.

 Overloaded by Ginny Smith is a beautifully insightful dive into how the brain functions. Smith does a good job of making the material relatable and readable despite discussing complex and sometimes difficult to understand scientific concepts. I would highly recommend this book to anyone interested in neuroscience or psychology or just anyone interested in how their brain works.

A seriously gifted presenter of science. Ginny Smith has an uncanny ability to make state-of-the-art medical insight simple, while retaining subtlety - and not going beyond what the research suggests. Her playful narrative style... is sure to amuse. Ginny Smith carefully navigates the topic without resorting to lifeless determinism or the ‘victim-blaming’ of free-will absolutists.

I have a degree in psychology and I still learned loads from Overloaded about the role all those "chemicals" have to play in so many areas of brain function! It does an excellent job of breaking down complex ideas clearly. Incredibly well-written and highly readable, I'll recommend it to students and friends equally!
