Barrett poses some interesting questions ... She writes with precision and clarity ... Barrett uses comparisons to everyday things and practices to help readers understand the brain’s complexity ... interesting concepts such as tuning (strengthening the connections between neurons) and pruning (when less-used connections weaken and die off) are presented in approachable ways ... Some topics are less fun but still worthy of consideration ... sheds some light on our most powerful organ and its intriguing processes.
