Why do we need to learn about this?

This spring we were able to share new information and stories with students through a deep dive into neuroscience. Northwest Noggin collaborated with volunteers studying different parts of the brain, and we visited public schools, community organizations and festivals. We were all able to share our knowledge by looking at real brains and anatomical models, and created our own brain cells from pipe cleaners, plants and ink. My particular interest is in psychology; so displaying these items and diving into the brain’s psyche with curious community members was particularly fun.

New Year in the Park celebrates Khmer, Thai, Lao and Myanmar culture, food and community, and this year many attendees were concerned about family separations and other cruel and aggressive actions by ICE. A beloved Lao-American food cart owner at Portland State had recently been abducted and detained by this violent (and deadly) federal agency.

Though our educational booth felt a little out of place at first (“wait what – real brains?!”), curious people of all ages approached us with tons of questions. One question made me realize that their curiosity was equalled by my own. Questions we answered from previous events had focused on education (for example, “Does the brain bleed?” or “Does the neuron have to curl at the end?”).

My first thought was there is no requirement for anyone to learn about anything. Out of context this sounds ridiculous and it is. The truth is that the brain decides to learn because its curiosity about something beyond comprehension is piqued. What motivates you is perhaps different than what motivates me. The reason to learn is up to the individual as all brains are wired differently.

LEARN MORE: How Does the Brain Make Decisions?

My students would ask me very similar questions. “Why do you like the color green?” “Why does she not like her spaghetti?” I usually responded by asking them to describe their own preferences. Why did THEY like some things, but not others? Why did some things interest them, and make them excited and curious?

So why do we have preferences?

My response was partly rooted in not wanting to dive too deep with three year olds (so many questions!), but it also stemmed from my own lack of knowledge about the brain. My classes on psychology and neuroscience at Portland State have offered me more in depth information and insight into how the brain works. Preferences can stem from prior experiences that made your brain happy. Situations that recall what you know to be satisfactory can make you gravitate towards something similar.

So why doesn’t “the brain” know?

Dresp-Langley (2011) states, “Our brain learns to perceive and represent the physical world a long time before we become phenomenally conscious.” Much of what we do and respond to is rapid and reflexive, relying on evolutionarily ancient systems, often found in subcortical structures deeper in the middle of the brain, below (sub) the wrinkled outer cortex. The world is full of compelling things, and our nervous systems respond to many without our conscious awareness or attention. Yet those implicit responses will generate changes in our felt sense of ourselves and the world, and influence our behavior.

But why do we wonder why?

That girl from outreach, the three year olds in my classroom, and my fellow volunteers and I are all curious about the world around us. One reason we seek answers can be attributed to survival. Kidd and Hayden (2015) note that, “the most popular theory about the function of curiosity is to motivate learning.” Learning about the world actually keeps us alive, or as Gottlieb (2024) puts it, “to encourage living things to explore their world in ways that help them survive.”

However, what I observed, shared and discovered during this outreach means a lot to me. I love seeing where curiosity can lead.

It was all of us volunteers sitting in public classrooms and learning about incredible student interests. It was the people of all ages wondering what we knew and were still finding out about our brains and behavior through this ongoing neuroscience research. It was letting our driving curiosity turn into into new stories, more knowledge, great art – and shared community.
