Affective Neuroscience: The Emotional Systems That Move Us

Before we think, we’ve already moved! 

For much of the history of psychology and neuroscience, emotion was treated as something that happened alongside, or sometimes interfered with, thinking.

Affective Neuroscience asks us to look at this differently.

Rather than beginning with conscious thoughts and asking how emotions influence them, it asks a more fundamental question:

What makes things matter to us in the first place?

Why do we move towards some things and away from others? Why do we protect, nurture, explore, play, protest or seek connection? Why can the same situation feel safe to one person and threatening to another?

These questions sit at the intersection of evolution, neuroscience, psychology and behaviour.

The idea that emotions have an evolutionary history is not new. Charles Darwin argued in The Expression of the Emotions in Man and Animals back in 1872 that emotional expression should be understood in the context of evolution, drawing attention to commonalities between human and animal behaviour. Later thinkers, including William James in the 1880s and Walter Cannon in the 1920s, developed competing accounts of the relationship between bodily change, brain activity and conscious emotional experience.

But during much of the twentieth century, the scientific study of emotion remained difficult. Feelings are tricky, primarily because they are subjective. They cannot be observed directly in another person, still less in another species. Behaviour can be measured, but behaviour alone does not tell us precisely what anything, or indeed anyone, is experiencing.

Neuroscientist Jaak Panksepp introduced what he called Affective Neuroscience to address this problem.

Panksepp argued that understanding emotion required looking beneath human language and conscious description towards older neural systems that humans share, to varying degrees, with other mammals. Instead of asking people only how they felt, he studied what happened when particular brain systems were stimulated, inhibited or disrupted, and he did this across different species.

From this work, Panksepp proposed that mammals share a number of evolutionarily conserved primary-process emotional systems. He eventually described seven:

SEEKING, RAGE, FEAR, LUST, CARE, PANIC/GRIEF and PLAY.

These systems are also reflected in the way Motional is designed. Our Domains and Subdomains draw, in part, on Panksepp’s framework, including CARE, SEEKING, PLAY, RAGE, FEAR and PANIC/GRIEF, alongside broader areas concerned with Emotional Regulation, Thinking and Concentration, Sense of Self, Relationship with Others and Emotional Literacy.

Motional does not treat Panksepp’s model as a complete account of Emotional Wellbeing. Rather, it provides one important part of the framework through which we organise and understand patterns of strength and need.

The capitalisation was deliberate. Panksepp was not claiming that a system labelled FEAR is identical to the rich, conscious human experience described by the everyday word fear. The labels were intended to identify underlying brain systems associated with characteristic patterns of motivation, affect and action.

This distinction matters.

A child experiencing something we describe as fear is not simply having a “FEAR circuit” switched on. Their experience emerges from bodily signals and ancient defensive systems, sometimes referred to as the “downstairs” brain, interacting continuously with memory, learning, prediction, context and the meanings built through experience, often associated with higher-order cortical processing or referred to pedagogically as the “upstairs” brain.

A Foundational Principle

As we explore the foundations underpinning Motional, we will encounter theories and models that are aligned in some areas, divergent in others, and sometimes genuinely competing.

A good example is the familiar pedagogical idea of the “upstairs” and “downstairs” brain, which offers a useful shorthand for thinking about regulation and higher-order processing. Similarly, the Triune Brain model has been widely adapted to describe “reptilian”, “mammalian” and “human” layers of brain development and function.

These can be useful ways of communicating complex ideas, but they should not be treated as literal maps of the brain. In particular, the Triune Brain model does not reflect contemporary understanding of how the brain evolved or how emotion and cognition interact.

Panksepp’s account offers a different model. He described interacting primary, secondary and tertiary processes: primary affective processes, secondary processes involving learning and memory, and tertiary processes involving higher-order cognition and reflection. Importantly, these processes interact continuously rather than representing three independent “levels” of brain functioning.

Our approach is not to choose a convenient model and present it as fact. We acknowledge where theories differ, look at the evidence behind them, and use models where they help us understand experience and develop better support, without overstating what neuroscience can tell us.

Panksepp’s contribution was therefore not to reduce emotion to seven ‘buttons’ in the brain. It was to argue that emotion has deep biological foundations, and that some of the systems shaping what mammals approach or ‘move towards’, avoid or ‘run from’, protect and seek are much older than human language, reflective thought or reasoning.

Panksepp’s ideas have been hugely influential, but they are not the only way of thinking about emotion. Other researchers have challenged parts of his model or described the same territory differently.

Joseph LeDoux, whose work transformed understanding of the neural mechanisms involved in responses to threat, has increasingly argued for an important separation between the brain systems that detect and respond to danger and the conscious human experience we call fear. From this perspective, conserved defensive survival circuits can initiate behavioural and physiological responses without themselves constituting the subjective feeling of fear, reinforcing the idea that FEAR (the brain system and linked bodily response) is separate from fear (the lived experience).

In an educational context, this distinction matters. For instance, a child may become avoidant, agitated, withdrawn, oppositional or physically dysregulated in response to perceived threat without having a clear, conscious explanation for what is happening. Asking, “What are you scared of?” may therefore be useful sometimes, but it may not.

So we need to pay attention not only to what a child can tell us, but also to patterns in their behaviour, physiology, relationship and environment.

Lisa Feldman Barrett offers another important challenge to simple accounts of biologically fixed emotion categories. Her Theory of Constructed Emotion proposes that emotional experience emerges through the brain’s ongoing prediction and interpretation of bodily and sensory information, drawing on previous experience and learned concepts. Constructed Emotion suggests that anger, sadness or fear do not each have one fixed pattern or system in the brain.

(We explore the brain’s predictive processes in more detail in Motional Foundation 1: Building Better Predictions.)

In an educational context, this matters because the same outward behaviour may reflect very different internal experiences. A clenched fist, refusal to engage or rapid breathing might be interpreted as anger, anxiety, frustration, excitement or something else entirely, depending on the child, the context and their previous experience.

So we should be cautious about labelling emotion from behaviour alone. Understanding comes from looking for patterns, paying attention to context and, crucially, building understanding through relationship, rather than assuming that a particular behaviour always means the same thing.

These perspectives are not identical, and some of their differences are substantial.

But there is an important thread running through them: emotion is not something we can neatly separate from the body, learning, experience and action.

Affective systems help shape what gets our attention, what we move towards, what we avoid and who we turn to.

But they do not, on their own, explain behaviour.

They are part of the biological foundations from which increasingly complex emotional lives develop.

Understanding those foundations gives us another way to look beneath behaviour.

Not to label a child.

Not to decide which emotional “system” they are in.

But to become more curious about what may be moving them.

Acknowledging the Evidence

Motional Foundations brings together evidence from multiple disciplines to explore how Emotional Wellbeing develops and how that understanding can inform practice.

This Foundation draws particularly on the work of Jaak Panksepp, whose work in Affective Neuroscience proposed a number of evolutionarily conserved primary emotional systems and helped establish emotion as a serious area of cross-species neuroscientific study. His ideas are considered alongside later work from researchers including Joseph LeDoux and Lisa Feldman Barrett, whose theories challenge, refine and sometimes differ substantially from Panksepp’s account.

The science of emotion is still developing, and no single, universally accepted model completely explains how emotional experience emerges from the brain and body. Motional therefore uses these theories as frameworks for understanding behaviour and Emotional Wellbeing, rather than treating any one of them as a complete or settled explanation.
