In the Healey Lab we study rapid estrogen signalling in the forebrain. We primarily focus on songbirds to understand how hormones modulate sensorimotor circuits for learning and sensory processing. Our experiments integrate behavior, neural circuits, physiology, anatomy, and molecular biology. We are grateful for research support from the U.S. National Institutes of Health and the National Science Foundation.

Research in the Healey lab is focused on the neural basis of natural behavior. We study songbirds as our research model for understanding vocal learning and brain plasticity. Over 50 years of intensive study of songbird behavior and brain function have provided a detailed roadmap of the neural circuits that are involved in singing, song learning, and audition (see diagram below). Our lab is interested in how neural circuits for vocal communication are modulated by the actions of local neurochemicals. For example, changing levels of brain estrogens can alter the pattern or 'tone' of neural circuit activity, enabling many flexible outputs from the same circuit. We think this modulation allows interconnected forebrain circuits to subserve a wide variety of complex behaviors, like singing, song learning, and song memory.

The song motor pathway contains circuits that directly pattern song output. Incoming sensory information is processed by HVC, and HVC initiates motor sequences that project out to the peripheral vocal organ, the syrinx, via RA and the hindbrain nucleus nXIIts. The auditory pathway : contains circuits that process sounds, including song. Auditory signals enter the brain at the cochlear nucleus (CN) and are further processed as they pass through the forebrain by nuclei such as NCM and CM. The forebrain loop pathway contains circuits that are important for song learning and song variability. HVC sends projections to a basal ganglia loop (striatal-thalamic-cortical-striatal) which has an important output projection to the song motor pathway at nucleus RA.



The forebrain of vocal learning species, such as humans and songbirds, has several features in common, including local production of steroid hormones (estrogens and androgens). Changes in local steroid levels within forebrain circuits can therefore influence communication behavior and vocal learning. We study these phenomena in songbirds using a variety of technical approaches including in vivo microdialysis, in vivo and in vitro electrophysiology, immunocytochemistry, and neuropharmacology. Songbirds offer a unique model system in which brain steroid production is widespread and especially pronounced, and in which the development and expression of a suite of social behaviors is accessible in the laboratory and natural environments.

Figure from Lee et al., J Neurophysiol, (2017) showing neural recordings from two brain regions (NCM and HVC) in response to sound playback of conspecific song (CON), bird's own song (BOS), and reverse-BOS (REV).

We use songbirds as a model of vocal learning and brain plasticity to examine questions such as:

  1. Why and how does the auditory cortex produce its own supply of estrogens?
  2. What neural and endocrine events occur when young birds learn to sing?
  3. What brain regions are important for song processing and song memory?
  4. What does the study of vocal learning in songbirds tell us about brain function in other vocal learning species, like human beings?

Why and how does the auditory cortex produce its own supply of estrogens?

Image of clustered neurons that synthesize estrogens (green) and the calcium-buffering protein parvalbumin (magenta) in the auditory cortex of zebra finches. (Ikeda et al., 2017)

Steroids, like estrogens and androgens, are produced within discrete neural circuits in the cortex of humans and songbirds. In songbirds, the estrogen-synthetic enzyme aromatase is expressed in both neuronal cell bodies and presynaptic boutons in the auditory cortex. Neuroestrogens can therefore influence behavior via local and acute actions within behavioral circuits. These actions are not well understood, in part because steroids have historically been associated with long-term events like puberty, seasonality, and sexual differentiation. Using a variety of methodological approaches we are testing the hypothesis that steroids act in a fast, localized manner very similar to neurotransmitters in the vertebrate nervous system.

We documented that the forebrain synthesizes estrogens during social encounters (Remage-Healey et al., 2008) in both males and females (Remage-Healey et al., 2012). More recently, we found that in females this is actually due to local synthesis of testosterone itself, the precursor to estrogens (de Bournonville et al., 2020). Therefore, somewhat unexpectedly, the male brain is making lots of the 'female hormone' estradiol, and the female brain in turn is making lots of the 'male hormone' testosterone!


What neural and endocrine events occur when young birds learn to sing?

An ensemble of neural, neurohormonal, and neurogenetic mechanisms are activated when adult songbirds hear auditory stimuli such as song. We are studying how these mechanisms contribute to the complex task of vocal learning in juvenile birds during development. Throughout the critical developmental stages of song learning we examine the electrical and neuromodulatory properties of neurons that contribute to song learning.

We subsequently documented that local blockade of neuroestrogen synthesis in one hemisphere of the auditory cortex did not impair song imitation accuracy (Vahaba et al., 2020). This indicates that estrogens may not be important for consoldiation of early vocal memories.

What brain regions are important for song processing and song memory?

The songbird forebrain contains a network of brain circuits that are involved in the highly complex process of singing. These structures are devoted to the processing of song, matching vocal output with neural templates, discriminating among individual song types, and storing long-term memories of individual songs. Our lab is investigating how the forebrain song circuit is modulated to enable these complex cognitive tasks. We have found that neurons express a specialized G-protein coupled estrogen receptor (GPER1) and that activation of this receptor is necessary for accurate encoding and processing of song in both males and females (Krentzel et al., 2018).

Using a task that asks the birds to teach themselves to learn new sounds, we found that blocking estrogen synthesis in the auditory cortex impairs their ability to associate new sounds with social rewards (Macedo-Lima and Remage-Healey, 2020). Therefore, in adulthood, learning complex sounds and their associations with natural consequences seems to depend on neuroestrogen signaling in the cortex.


What does the study of vocal learning in songbirds tell us about brain function in other vocal learning species, like human beings?

Songbirds learn to vocalize according to a developmental timeline that parallels the process of human speech learning. Shared principals include an early sensory phase (listening and classifying vocalizations and storing vocal memories), and a sensorimotor phase (‘babbling’ or practicing vocal elements and matching them against memorized sequences). Therefore, since zebra finches can be reared and studied in the laboratory they offer a rich and tractable model for studying the mechanisms of auditory and vocal learning. Our lab is particularly interested in how brain plasticity is guided and shaped by neurohormonal events. The ultimate goal of this work is to improve our understanding of how vocal communication circuits are connected and modulated.

The lab's codebase can be found on our github page.

Here are a few pieces of code we have been finding useful lately:

A routine for quickly converting Igor patch clamp traces into Python-readable formats, and plotting them

A routine for converting Kilosort timestamps (sorted spikes) into python formats and plotting rasters, PSTHs, and firing rates


We engage in outreach events, engaging community members in our research with hands-on activities both in the lab and in local schools and community events.


The lab is accepting motivated students from all academic backgrounds.

We have a current postdoctoral position opening! Find out more here.
